Product Description
The SOUL Muffler Bypass Pipes are designed for Porsche 997.1 Carrera owners who want maximum weight reduction and an uncompromising, CUP-inspired naturally aspirated flat-six exhaust note. By completely eliminating the heavy factory rear mufflers, the system transforms the character of the 997.1 while removing a substantial amount of weight from the rear of the vehicle.
SOUL uses a completely free-flowing design with 2.25-inch OD piping throughout the system. With no mufflers or significant sound attenuation in the exhaust path, the Muffler Bypass Pipes deliver an immediate and dramatic increase in volume, mechanical character, and flat-six intensity.
Weight reduction is one of the most significant benefits of this system. The factory rear exhaust components weigh approximately 38.5 lbs, while the SOUL Muffler Bypass Pipes weigh approximately 2 lbs without tips, saving approximately 36.5 lbs / 16.5 kg from the rear of the vehicle.
This is an intentionally aggressive exhaust system. With no mufflers present, cabin drone will be noticeable, and overall volume increases substantially when the system is combined with high-flow catalytic converters or cat bypass pipes. For owners looking for a lightweight, simple, and extremely aggressive street or track exhaust configuration, the SOUL Muffler Bypass Pipes provide one of the most dramatic sound and weight transformations available for the 997.1 Carrera.

MODEL / TIP CONFIGURATION:
The correct configuration must be selected based on the vehicle's model and existing exhaust system.
Carrera S / Carrera 4S / Targa 4S – Reuse Factory Tips:
S-model vehicles equipped with the standard non-PSE exhaust can reuse their factory exhaust tips. This is the lightest and most cost-effective configuration.
Base Carrera / Carrera 4 / Targa 4 / Any Model with Factory PSE – SOUL Tips:
Base-model vehicles and any 997.1 equipped with factory Porsche Sport Exhaust require SOUL exhaust tips because of differences in factory outlet diameter. This DasMotoring configuration includes SOUL Polished Chrome exhaust tips.
Owners of Carrera S, Carrera 4S, or Targa 4S models who prefer SOUL tips rather than reusing the factory tips can also select the SOUL-tip configuration.
SOUND CHARACTER:
The SOUL Muffler Bypass Pipes provide one of the most aggressive exhaust configurations available for the naturally aspirated 997.1 Carrera.
Removing the factory mufflers creates a raw, direct, CUP-inspired flat-six sound with substantially more volume throughout the rev range. Unlike a conventional performance muffler, there is no significant sound attenuation between the engine and the exhaust outlets.
The result is extremely engaging during spirited driving, but the tradeoff is increased cabin presence and noticeable drone during cruising.
Pairing the Muffler Bypass Pipes with SOUL Sport Catalytic Converters will further increase overall exhaust volume and character. Combining them with SOUL Cat Bypass Pipes creates an exceptionally loud complete exhaust configuration intended for owners who prioritize maximum sound over street refinement.
STREET USE / DRONE:
The SOUL Muffler Bypass Pipes contain no mufflers, and cabin drone should be expected.
SOUL notes that drone can be managed to some degree by selecting an appropriate cruising RPM, but owners should not expect the refinement of the Sport Side Mufflers or Valved Exhaust System.
For owners who want increased exhaust sound while retaining better highway comfort, the SOUL Sport Side Mufflers provide a more refined fixed-exhaust alternative. Owners who want maximum control over exhaust volume should consider the SOUL Valved Exhaust System.
TIP CONFIGURATION:
The SOUL-tip configuration includes Polished Chrome exhaust tips.
To keep ordering simple, DasMotoring does not offer additional tip-finish dropdowns on this listing. If you would like another currently available SOUL tip finish, contact DasMotoring before ordering and we can confirm availability and pricing.
NOTE: SOUL Carbon Fiber exhaust tips for this application have been discontinued.
MUFFLER BYPASS VS. SPORT SIDE MUFFLERS:
The SOUL Muffler Bypass Pipes completely eliminate the factory mufflers for maximum weight reduction and the most aggressive fixed exhaust sound.
The SOUL Sport Side Mufflers retain dedicated mufflers designed to increase flat-six character while controlling drone and maintaining a more refined OEM+ cruising experience.
For owners prioritizing minimum weight and maximum sound, the Muffler Bypass Pipes provide the more aggressive solution. For primarily street-driven cars where highway refinement remains important, the Sport Side Mufflers provide the more balanced alternative.

Product Description
The SOUL Competition Headers are designed for Porsche 997.1 Carrera owners looking to improve exhaust flow, engine response, and naturally aspirated flat-six performance while retaining the factory catalytic converter configuration. Unlike many header upgrades that remove or relocate catalytic converters, the 997.1 Carrera incorporates its catalytic converters farther downstream in the exhaust system, allowing SOUL to optimize the header design without affecting the factory emissions equipment.
SOUL developed the Competition Headers around a smoother exhaust path from the cylinder heads into the remainder of the system. Port-matched flanges, smooth-radius primary tubing, equal-length runners, and a true 3-into-1 merge collector improve upon the factory header geometry and provide a more efficient transition between the individual cylinders and downstream exhaust.
The design is particularly beneficial to the larger 3.8L Carrera S engine, which can take advantage of the additional exhaust volume, while also improving the flow path of the factory 3.6L Carrera engine. The result is improved exhaust flow and stronger torque response without introducing additional emissions concerns, catalyst-related fault codes, or unwanted changes in exhaust sound quality.
The SOUL Competition Headers also reduce weight compared with the factory components, saving approximately 2 lbs / 0.9 kg while providing a direct bolt-on performance upgrade.

HEADER DESIGN:
The factory 997.1 Carrera places its catalytic converters farther downstream in the exhaust system, allowing the header geometry itself to be optimized independently of the emissions-control components.
SOUL improves the exhaust path through equal-length runners, smooth-radius tubing, port-matched flanges, and a true 3-into-1 merge collector. This provides a smoother transition from the individual cylinders into the downstream exhaust system and reduces unnecessary restriction through the header assembly.
The design improves the flow characteristics of the 3.6L Carrera engine while providing the additional exhaust volume required by the larger 3.8L Carrera S engine.
CATALYTIC CONVERTERS / CHECK ENGINE LIGHT:
The SOUL Competition Headers do not remove the factory catalytic converters.
On the 997.1 Carrera, the catalytic converters are located downstream of the headers. Because the SOUL Competition Headers replace only the header assemblies, the factory emissions-control equipment can remain in place.
SOUL specifically designed the headers to improve exhaust flow without creating additional emissions concerns or catalyst-related check engine lights.
For owners looking for additional exhaust flow farther downstream, the headers can also be paired with SOUL Sport Catalytic Converters or other compatible exhaust components.
COMPETITION HEADERS + DOWNSTREAM EXHAUST:
The SOUL Competition Headers can be used as a standalone upgrade with the remainder of the factory exhaust system or incorporated into a more comprehensive exhaust configuration.
Pairing the headers with SOUL Sport Catalytic Converters can further reduce exhaust restriction while retaining catalytic converters.
For owners looking for additional exhaust sound, the headers can also be combined with SOUL Sport Side Mufflers or the SOUL Valved Exhaust System.
This modular approach allows owners to progressively upgrade the 997.1 exhaust system while selecting the desired balance of performance, sound, and street usability.
Product Description
The SOUL Cat Bypass Pipes are designed for Porsche 997.1 Carrera owners looking for maximum exhaust flow, substantial weight reduction, and the most aggressive naturally aspirated flat-six sound available from the center section of the exhaust system. By completely removing the restrictive factory catalytic converters, the Cat Bypass Pipes create a freer-flowing exhaust path while allowing significantly more of the engine's mechanical character to come through.
During development, SOUL compared a traditional X-pipe configuration with a separated-bank design. Testing showed that joining the banks with an X-pipe reduced some of the deeper frequencies that contribute to the distinctive 997.1 exhaust note. SOUL therefore chose to keep the left and right cylinder banks separated, producing a deeper and fuller flat-six sound with increased volume and a subtle hint of rasp reminiscent of earlier air-cooled Porsche exhaust systems.
The Cat Bypass Pipes are constructed from 2.25-inch OD, .065-inch-wall T304L stainless steel tubing with smooth mandrel bends and durable exhaust flanges. The complete assemblies weigh approximately 8.75 lbs, compared with approximately 15 lbs for the factory catalytic converter sections, reducing weight by approximately 6.25 lbs / 2.8 kg.
For owners prioritizing maximum exhaust flow, reduced weight, throttle response, and an uncompromising flat-six exhaust note, the SOUL Cat Bypass Pipes provide the most aggressive alternative to the factory catalytic converters.

SOUND CHARACTER:
SOUL specifically developed the 997.1 Cat Bypass Pipes around a separated-bank exhaust design rather than an X-pipe crossover.
During development, SOUL found that joining the exhaust banks with an X-pipe produced a hollower tone and removed some of the deeper frequencies that contribute to the character of the 997.1 flat-six.
Keeping the two banks separated adds more volume and preserves a deeper, fuller exhaust note with increased mechanical character and a subtle hint of rasp.
When paired with factory rear mufflers, the Cat Bypass Pipes provide a substantial increase in sound while allowing the factory mufflers to continue controlling overall volume.
Pairing the Cat Bypass Pipes with SOUL Sport Side Mufflers or the SOUL Valved Exhaust System will create a significantly more aggressive complete exhaust configuration.
CHECK ENGINE LIGHT / ECU TUNING:
The SOUL Cat Bypass Pipes completely remove the factory catalytic converters and may trigger a check engine light as a result.
An appropriate ECU calibration can be used to address catalyst-related fault codes and may also allow the engine management system to better accommodate the freer-flowing exhaust configuration.
Customers should plan for the possibility of a check engine light when installing this product.
EXISTING EXHAUST CONFIGURATION:
The 997.1 Carrera uses different Cat Bypass Pipe configurations depending on whether the vehicle was originally equipped with the standard exhaust or Porsche Sport Exhaust (PSE).
The correct rear exhaust configuration must be selected when ordering:
Non-PSE / Standard Factory Exhaust
Factory Porsche Sport Exhaust (PSE)
CAT BYPASS VS. SPORT CATALYTIC CONVERTERS:
The SOUL Cat Bypass Pipes completely eliminate the factory catalytic converters for the least restrictive exhaust path, greater weight reduction, and the most aggressive exhaust note.
The SOUL Sport Catalytic Converters retain high-flow catalysts while still improving exhaust flow, throttle response, power, and flat-six sound.
For owners prioritizing maximum flow, minimum weight, and sound—and who are prepared to address catalyst-related fault codes—the Cat Bypass Pipes provide the more aggressive configuration. For owners who want improved performance while retaining catalytic converters, the Sport Catalytic Converters provide the more street-oriented alternative.
EMISSIONS / USE NOTE:
The SOUL Cat Bypass Pipes remove the factory catalytic converters and are not CARB certified.
This product may not be legal for use on emissions-controlled vehicles and is intended for off-road / competition use only due to removal of the factory catalytic converters.
Customers are responsible for ensuring compliance with all applicable local, state, and federal regulations before installation or use.
Product Description
The SOUL Sport Catalytic Converters are designed for Porsche 997.1 Carrera owners looking to improve exhaust flow, throttle response, power, and naturally aspirated flat-six sound while retaining catalytic converters. The factory 997.1 catalytic converters are a significant restriction in the exhaust system, making this one of the most effective upgrades for owners who want additional performance and sound without moving to a fully catless configuration.
Rather than joining the two cylinder banks with an X-pipe, SOUL intentionally keeps the exhaust banks separated through the catalytic converter sections. During development, SOUL compared both configurations and found that the separate-bank design retained more of the deep frequencies and mechanical character of the 997.1 flat-six. The result is a deeper, fuller exhaust note with increased volume and a subtle hint of rasp reminiscent of earlier air-cooled Porsche exhaust systems.
Independent Dynojet testing performed by Growler Motor Labs demonstrated repeatable peak gains of approximately 10 wheel horsepower and 14 lb-ft of torque, along with noticeable improvement through the midrange. SOUL also reports improved throttle response and overall drivability.
The Sport Catalytic Converters reduce weight compared with the factory components as well. The factory catalytic converter sections weigh approximately 15 lbs, while the SOUL assemblies weigh approximately 13 lbs, saving approximately 2 lbs / 0.9 kg.
For owners looking for increased power, improved response, and a more engaging flat-six exhaust note while retaining catalytic converters and avoiding the compromises of a fully catless system, the SOUL Sport Catalytic Converters provide a strong street-oriented upgrade.

EXHAUST SOUND:
SOUL specifically evaluated both separated-bank and X-pipe configurations when developing the 997.1 Sport Catalytic Converters.
SOUL found that incorporating an X-pipe into this section reduced overall volume and removed some of the deeper frequencies that contribute to the distinctive 997.1 flat-six sound.
The production Sport Catalytic Converters therefore retain separate left and right exhaust banks, producing a deeper, fuller exhaust note with more mechanical character and a subtle hint of rasp.
When paired with the factory rear mufflers, the result is an increase in sound and character while retaining much of the refinement of the original exhaust system.
Pairing the Sport Catalytic Converters with SOUL Sport Side Mufflers or the SOUL Valved Exhaust System will further increase overall exhaust volume and character.
CHECK ENGINE LIGHT:
The SOUL Sport Catalytic Converters are designed to increase exhaust flow and performance while retaining effective catalytic conversion.
SOUL specifically developed this system to provide additional power and sound without triggering a check engine light under normal operating conditions.
As with any emissions-related component, vehicle condition, oxygen-sensor health, ECU calibration, and additional modifications can influence catalyst monitoring. DasMotoring does not guarantee that a check engine light can never occur.
EXISTING EXHAUST CONFIGURATION:
The 997.1 Carrera uses different catalytic converter configurations depending on whether the vehicle was originally equipped with standard exhaust or Porsche Sport Exhaust (PSE).
The correct configuration must be selected when ordering:
Non-PSE / Standard Factory Exhaust
Factory Porsche Sport Exhaust (PSE)
SPORT CAT VS. CAT BYPASS:
The SOUL Sport Catalytic Converters retain high-flow catalytic converters while improving exhaust flow, power, throttle response, and flat-six sound.
The SOUL Cat Bypass Pipes eliminate the catalytic converters entirely for a lighter, less restrictive, and substantially more aggressive exhaust configuration.
For owners who want increased performance and sound while retaining catalytic converters and SOUL's no-CEL design intent, the Sport Catalytic Converters provide the more street-oriented solution. For vehicles built around a fully catless exhaust configuration, the Cat Bypass Pipes provide the more aggressive alternative.
EMISSIONS / USE NOTE:
These components replace factory emissions-control equipment with aftermarket high-flow catalytic converters.
Aftermarket catalytic converter regulations vary by jurisdiction, and retaining catalytic converters does not necessarily mean an aftermarket component is approved for use on emissions-controlled vehicles in every location.
Customers are responsible for confirming compliance with all applicable local, state, and federal regulations before installation or use.
Product Description
The SOUL Competition X-Pipe is designed for Porsche 997.1 Carrera owners looking to reduce exhaust restriction, decrease weight, and add a more aggressive naturally aspirated flat-six exhaust character. Replacing the factory center exhaust section with a freer-flowing X-pipe architecture improves exhaust flow through one of the most restrictive areas of the factory system.
SOUL developed the Competition X-Pipe around large-diameter mandrel-bent tubing and a crossover designed to improve flow between the two cylinder banks. The result is a lighter and less restrictive center exhaust section that works with both factory and upgraded rear mufflers.
Weight reduction is significant for a relatively compact exhaust component. The factory center section weighs approximately 15.65 lbs, while the SOUL Competition X-Pipe weighs approximately 10 lbs, saving approximately 5.65 lbs / 2.5 kg.
The Competition X-Pipe is a direct bolt-on upgrade and is compatible with vehicles equipped with or without factory Porsche Sport Exhaust.

EMISSIONS / USE NOTE:
The SOUL Competition X-Pipe is an aftermarket exhaust component and is not CARB certified.
Customers are responsible for confirming compliance with all applicable local, state, and federal emissions regulations before installation or use.
Product Description
The SOUL Sport Cat X-Pipe is designed for Porsche 997.1 Carrera owners looking to improve exhaust flow, engine response, performance, and naturally aspirated flat-six sound while retaining catalytic converters. Replacing the restrictive factory center exhaust section with a freer-flowing X-pipe and high-flow catalytic converters opens one of the major restrictions in the factory exhaust system without moving to a fully catless configuration.
SOUL developed the system around large-diameter exhaust tubing and an X-pipe crossover designed to improve flow between the two cylinder banks. The crossover helps blend exhaust pulses from each bank while reducing restriction through the center section, resulting in a stronger and more engaging flat-six exhaust character.
At the center of the system are SOUL-designed 200-cell high-flow catalytic converters. These catalysts use a custom-specified precious-metal coating and a triple metal-matrix core, providing significantly greater exhaust flow than the factory catalytic converters while retaining a catted exhaust configuration.
The SOUL Sport Cat X-Pipe also provides a modest reduction in weight. The factory components weigh approximately 15.65 lbs, while the SOUL assembly weighs approximately 13.5 lbs, saving approximately 2.15 lbs / 1.0 kg.
For owners looking to improve exhaust flow and naturally aspirated flat-six sound while retaining high-flow catalytic converters, the SOUL Sport Cat X-Pipe provides a strong street-oriented upgrade that pairs well with either the factory rear mufflers or an upgraded SOUL exhaust system.

Compared with the restrictive factory catalytic converters, the SOUL 200-cell catalysts allow substantially greater exhaust flow while maintaining catalytic converters within the exhaust system.
SOUND CHARACTER:
Replacing the factory center section with the SOUL Sport Cat X-Pipe increases exhaust character throughout the rev range while allowing the rear muffler configuration to determine much of the system's overall volume.
When paired with the factory rear mufflers, the Sport Cat X-Pipe provides a more aggressive and engaging version of the factory exhaust character.
Pairing the X-pipe with SOUL Sport Side Mufflers or the SOUL Valved Exhaust System further increases overall exhaust volume and allows substantially more of the naturally aspirated flat-six sound to come through.
SPORT CAT X-PIPE VS. FACTORY CENTER SECTION:
The factory center exhaust section prioritizes emissions compliance and noise control, resulting in significant restriction through the catalytic converters.
The SOUL Sport Cat X-Pipe replaces this section with large-diameter piping, an X-pipe crossover, and 200-cell high-flow catalytic converters, improving exhaust flow while retaining catalytic converters.
For owners looking for increased performance and sound without converting the vehicle to a fully catless configuration, the Sport Cat X-Pipe provides the more street-oriented solution.
EMISSIONS / USE NOTE:
This product replaces factory emissions-control components with aftermarket high-flow catalytic converters.
Aftermarket catalytic converter regulations vary by jurisdiction, and retaining catalytic converters does not necessarily make an aftermarket exhaust component legal for use on emissions-controlled vehicles in every location.
Customers are responsible for confirming compliance with all applicable local, state, and federal regulations before installation or use.
Product Description
The SOUL Sport Side Mufflers are designed for Porsche 997.1 Carrera owners who want a noticeably more engaging flat-six exhaust note while maintaining the refinement expected from a street-driven 911. Rather than chasing maximum volume, SOUL developed these mufflers to emphasize the mechanical character and tone of the naturally aspirated engine without introducing excessive rasp or highway drone.
During moderate and aggressive throttle, the Sport Side Mufflers increase exhaust volume and allow significantly more of the flat-six character to come through. During steady-speed cruising and light-throttle driving, SOUL's proprietary mufflers maintain a refined, OEM+ cabin presence designed for comfortable everyday use.
SOUL developed the Sport Side Mufflers alongside its high-flow Sport Catalytic Converters, allowing the system to remain controlled even when additional exhaust restriction is removed upstream. This makes the mufflers particularly well suited for owners who want to progressively upgrade the complete exhaust system without ending up with an excessively harsh or raspy combination.
The complete SOUL muffler assembly weighs approximately 29.7 lbs, compared with approximately 34.8 lbs for the factory exhaust components, reducing weight by approximately 5.1 lbs / 2.3 kg.

SOUND CHARACTER:
The SOUL Sport Side Mufflers are designed around sound quality rather than maximum volume.
Under moderate and aggressive throttle, the system emphasizes the mechanical tone and naturally aspirated character of the 997.1 flat-six. During steady cruising, the proprietary mufflers provide a more restrained OEM+ presence while helping prevent the drone and harsh rasp that can occur with more aggressive muffler designs.
SOUL specifically developed these mufflers with high-flow catalytic converters in mind, making them a strong choice for owners who want additional exhaust volume without turning the car into an overly loud street setup.
STANDARD EXHAUST / PSE FITMENT:
The SOUL Sport Side Mufflers can be used on 997.1 Carrera models originally equipped with either the standard exhaust or factory Porsche Sport Exhaust.
Base Carrera models and vehicles converting from factory PSE must use SOUL exhaust tips for proper fitment.
To eliminate fitment ambiguity, this DasMotoring listing includes SOUL exhaust tips rather than relying on the customer's existing factory tips.
TIP CONFIGURATION:
This DasMotoring listing includes SOUL Polished Chrome exhaust tips.
To keep ordering simple and ensure compatibility across the 997.1 Carrera range, alternate tip options are not offered through the standard product dropdowns.

Product Description
The SOUL Valved Exhaust System is designed for Porsche 997.1 Carrera owners who want a genuine change in exhaust character at the press of a button. With the valves closed, the system delivers a refined, sporty OEM+ sound with excellent cruising comfort. Open the valves and the character changes dramatically, providing a freer-flowing, race-inspired exhaust note that allows substantially more of the naturally aspirated flat-six sound to come through.
SOUL developed the system specifically around the 997.1 Carrera platform, applying the same muffler design principles used throughout its Porsche exhaust lineup to minimize unwanted cabin drone. With the valves closed, exhaust gases are routed through SOUL's bespoke mufflers for a sophisticated and controlled exhaust note. This is also the default position when the vehicle is started, providing a more refined cold-start and warm-up experience.
With the valves open, the system bypasses the primary muffled exhaust path and delivers a substantially louder, freer-flowing sound. SOUL describes the resulting tone as inspired by air-cooled Porsche Cup cars, providing a much more aggressive experience during spirited driving while retaining the ability to return the car to a quieter configuration whenever desired.
The complete SOUL system weighs approximately 36.6 lbs, compared with approximately 38.6 lbs for the factory exhaust components, reducing weight by approximately 2 lbs / 0.9 kg.
FITMENT:
Fits 2005–2008 Porsche 997.1 Carrera and Carrera S Coupe and Cabriolet models
Fits 2006–2008 Porsche 997.1 Carrera 4 and Carrera 4S Coupe and Cabriolet models

VALVE OPERATION:
The SOUL Valved Exhaust defaults to the valves-closed position every time the vehicle is started. This provides a quieter and more refined startup before the driver chooses to open the valves.
Valve operation is controlled using the included SOUL remotes and can also be programmed to compatible factory HomeLink buttons, allowing convenient control from inside the vehicle.
With the valves closed, SOUL designed the system specifically to eliminate objectionable cruising drone. Opening the valves provides the system's substantially louder and more aggressive race-inspired exhaust mode.
EXISTING EXHAUST CONFIGURATION:
The SOUL Valved Exhaust is available for both non-PSE vehicles and vehicles originally equipped with factory Porsche Sport Exhaust.
Because the factory exhaust and tip configurations differ, the customer's existing exhaust configuration must be selected when ordering to ensure the correct SOUL system is supplied.
Available configurations:
Non-PSE / Standard Factory Exhaust
Factory Porsche Sport Exhaust (PSE)
TIP CONFIGURATION:
This DasMotoring listing includes SOUL Polished Chrome exhaust tips.
Using SOUL tips provides a consistent fitment solution across the 997.1 Carrera range. SOUL specifically notes that certain base Carrera applications and vehicles originally equipped with factory PSE require SOUL exhaust tips for proper fitment.
To keep ordering simple, alternate tip finishes are not offered through the standard product options. If you would like another available SOUL tip finish, contact DasMotoring before ordering and we can confirm availability and pricing.
NOTE: SOUL has discontinued its Carbon Fiber tips for this system.
SOUND WITH AFTERMARKET CATALYTIC CONVERTERS:
The SOUL Valved Exhaust is designed to remain refined with the valves closed even when paired with aftermarket catalytic converters.
With the valves open, however, high-flow catalytic converters or catless replacement components will significantly increase overall exhaust volume. Customers building a complete exhaust system should consider the combined sound level of all components rather than evaluating the rear mufflers independently.
