Porsche 991.2 Carrera with PSE SOUL Valved Exhaust System

Product Description

The SOUL Valved Exhaust System is a complete rear exhaust upgrade for 2017–2019 Porsche 991.2 Carrera models equipped with Porsche Sport Exhaust / PSE, engineered to dramatically improve the sound of the turbocharged 3.0L flat-six while retaining the everyday usability and factory-controlled valve functionality of the original Porsche system.

SOUL developed the exhaust around two distinct flow paths. With the valves open, exhaust flows through a large 3-inch chambered X-pipe, blending the two cylinder banks for a smoother, higher-pitched exhaust note while maximizing available exhaust flow. With the valves closed, exhaust is redirected through a smaller 1.75-inch secondary path incorporating two large resonators, substantially reducing sound level and low-RPM drone for comfortable cruising.

The system integrates with the factory Porsche Sport Exhaust controls, allowing Porsche's original PSE programming to continue managing valve operation based on the selected driving mode and operating conditions.

At approximately 20 lbs, the SOUL system is also approximately 3 lbs / 1.3 kg lighter than the 23-lb factory rear exhaust.

DUAL-FLOW EXHAUST DESIGN:

The defining feature of SOUL's Valved Exhaust System is its use of two purpose-built exhaust paths.

Rather than simply placing valves inside an otherwise conventional muffler, SOUL designed separate flow strategies for aggressive and subdued operation.

Valves Open:

Exhaust flows through the large 3-inch chambered X-pipe, prioritizing maximum sound and flow.

Valves Closed:

Exhaust is redirected through a 1.75-inch secondary path containing two large resonators, significantly reducing sound level and low-RPM resonance.

This gives the car a genuine change in character rather than simply a small change in exhaust volume.

3-INCH PRIMARY FLOW PATH:

With the valves open, the SOUL system provides a full:

3-inch primary exhaust path

through the chambered X-pipe.

The larger flow path is designed to reduce downstream restriction and maximize flow potential from the turbocharged engine.

This becomes increasingly useful as airflow demand increases through modifications such as:

• ECU tuning

• Sport catalytic converters

• Cat bypass pipes

• Sport headers

• Upgraded turbochargers

Even on an otherwise stock car, the larger X-pipe architecture significantly changes the character of the factory exhaust.

CHAMBERED X-PIPE:

The factory PSE architecture does relatively little to blend the exhaust pulses from the opposing cylinder banks when operating through its primary flow path.

SOUL replaces this arrangement with a purpose-designed chambered X-pipe.

The X-pipe allows the two exhaust streams to interact and blend before exiting the vehicle.

SOUL developed the design to produce:

• Smoother exhaust character

• Higher-pitched tone under load

• Better cylinder-bank blending

• Increased exhaust-flow capability

• More pronounced turbocharged flat-six character

The chamber itself is designed to blend the streams without substantially reducing the effective diameter of the primary exhaust path.

VALVES OPEN:

With the factory PSE valves commanded open, exhaust is directed through the unrestricted 3-inch primary X-pipe path.

Expect:

• Significantly greater exhaust volume than stock

• Richer and more robust exhaust tone

• Smoother cylinder-bank blending

• Higher-pitched character under load

• Greater turbocharged flat-six presence

• More pronounced turbo spool and exhaust sound

• Dramatic full-throttle character

• Stronger pops and burbles in Sport mode

• Increased acoustic response to throttle input

SOUL specifically developed the system to provide significantly more character than the original PSE exhaust without making the car unnecessarily aggressive for street use.

VALVES CLOSED:

SOUL put substantial engineering effort into making the quieter mode meaningfully different from the aggressive valves-open mode.

When the valves close, exhaust is redirected through a:

1.75-inch secondary flow path

containing:

Two large resonators

The reduced-diameter secondary path limits overall sound, while the resonators further suppress undesirable frequencies.

Expect:

• Significantly lower exterior volume

• Reduced low-RPM exhaust presence

• Reduced cabin drone

• More civilized everyday operation

• Comfortable highway cruising

• Meaningful separation from the valves-open sound

• Improved flow compared with the factory rear muffler despite the quieter configuration

This allows the car to remain understated when desired while keeping the more dramatic valves-open character immediately available.

DUAL RESONATOR SYSTEM:

Packaging constraints in the 991.2 Carrera rear exhaust make incorporating a conventional large muffler into SOUL's secondary path difficult.

Rather than simply reducing pipe diameter, SOUL uses a pair of large resonators.

The resonators are designed to:

• Reduce overall sound level

• Smooth low-frequency exhaust resonance

• Reduce unwanted drone

• Work against each other's exhaust pulses

• Improve valves-closed refinement

This allows the secondary path to maintain useful exhaust flow while providing substantially greater acoustic control.

FACTORY PSE INTEGRATION:

The SOUL Valved Exhaust System is designed specifically for cars already equipped with Porsche Sport Exhaust.

It reuses Porsche's existing exhaust-valve controls rather than requiring a separate aftermarket valve controller.

The factory PSE programming continues controlling exhaust-valve behavior based on:

• Selected driving mode

• Engine RPM

• Engine operating conditions

As RPM and load increase, Porsche's programming can progressively make greater use of the freer-flowing primary exhaust path.

NO SEPARATE VALVE CONTROLLER REQUIRED:

Because the car already contains Porsche's PSE valve-control infrastructure, there is no need to add:

• Aftermarket remotes

• Additional valve-control electronics

• HomeLink programming

• Separate vacuum-control logic

This makes the installation and operation cleaner than converting a non-PSE Carrera to a valved aftermarket exhaust.

NORMAL / EVERYDAY DRIVING:

During relaxed driving, the secondary resonated flow path gives the car a substantially more civilized personality.

SOUL's goal was to preserve:

• Highway comfort

• Conversation-friendly cabin volume

• Reduced drone

• Neighborhood-friendly operation

while still providing more exhaust character than the factory system.

The system is not designed to make the car silent with the valves closed; it is designed to provide a clear and useful reduction in presence relative to the valves-open configuration.

SPORT MODE:

The exhaust's more aggressive side becomes especially apparent in Porsche's Sport mode.

The combination of:

• Factory PSE programming

• Factory Sport-mode engine calibration

• 3-inch X-pipe

• Greater exhaust flow

allows the factory-generated pops and burbles to become substantially more pronounced.

This gives the 991.2 Carrera considerably more of the theatrical character that many owners feel is missing from the original turbocharged exhaust system.

SOUND CHARACTER:

The SOUL Valved Exhaust System is designed to move the 991.2 Carrera away from the muted tone of the factory PSE system.

Expect a sound profile that is:

• Richer

• Smoother

• More robust

• Higher pitched under load

• More aggressive at higher RPM

• More responsive to throttle input

• More pronounced during gear changes and downshifts

• More expressive in Sport mode

At the same time, the valved secondary path provides the ability to substantially reduce sound during normal cruising.

COMPATIBLE WITH SOUL SPORT CATALYTIC CONVERTERS:

SOUL developed the Valved Exhaust System on a vehicle already equipped with upgraded exhaust components, including Sport Catalytic Converters.

Pairing the two systems provides:

• Increased upstream exhaust flow

• Reduced catalyst restriction

• Increased turbocharger sound

• More aggressive exhaust tone

• Full 3-inch valves-open rear flow path

• Retained factory PSE valve control

• Retained quieter valves-closed behavior

The combination creates a more comprehensive performance exhaust while retaining catalytic converters.

COMPATIBLE WITH SOUL SPORT HEADERS:

SOUL's development vehicle also incorporated upgraded headers.

The Valved Exhaust was therefore specifically evaluated in a higher-flowing exhaust configuration rather than only on a completely stock vehicle.

This is important because an exhaust that remains comfortable with factory components can sometimes become excessively loud or develop drone once upstream restrictions are removed.

SOUL designed the secondary resonated path with these more aggressive configurations in mind.

WITH CAT BYPASS PIPES:

The Valved Exhaust can also be combined with catless bypass pipes for a substantially more aggressive configuration.

Removing the factory catalytic converters will significantly increase:

• Exhaust volume

• Turbocharger sound

• Exhaust flow

• Pops and burbles

• Overall acoustic intensity

The rear exhaust itself remains valved, but the complete system will be substantially louder due to the upstream catalyst removal.

Applicable emissions and ECU considerations should be addressed separately for the catless components.

3-LB WEIGHT REDUCTION:

SOUL publishes the following weights:

Factory Rear Exhaust:
Approximately 23 lbs / 10.4 kg

SOUL Valved Exhaust:
Approximately 20 lbs / 9.1 kg

Weight Savings:
Approximately 3 lbs / 1.3 kg

The weight reduction is modest compared with some muffler-bypass systems, but the SOUL system retains a sophisticated dual-path valved architecture and significant sound-control capability.

.065-INCH T304L STAINLESS CONSTRUCTION:

The system is fabricated from:

.065-inch-wall T304L stainless steel

This construction is intended to provide:

• High-temperature durability

• Corrosion resistance

• Structural strength

• Long-term reliability

• Consistent exhaust geometry

The finished assemblies are quality checked in-house before shipment.

BOLT-ON INSTALLATION:

SOUL builds and checks each exhaust in a dedicated fixture before shipment to ensure consistent fitment.

The system includes the hardware necessary for installation and is designed as a bolt-on replacement for the factory PSE rear exhaust.

There is no need to modify:

• ECU calibration

• Catalytic converters

• Oxygen sensors

• Factory PSE electronics

for installation of the rear exhaust itself.

PERFORMANCE:

The 3-inch primary path provides substantially more available exhaust-flow capacity than the restrictive factory rear muffler architecture.

SOUL describes the system as maximizing flow for performance potential and notes that even the valves-closed secondary path improves flow relative to the factory muffler.

However, SOUL does not currently publish a controlled standalone horsepower or torque figure for this rear exhaust.

DasMotoring therefore does not advertise a numerical power increase for the Valved Exhaust System by itself.

VALVED EXHAUST VS. SOUL NON-VALVED X-PIPE:

SOUL Valved Exhaust System

• $3,795.00

• 3-inch primary X-pipe path

• 1.75-inch secondary flow path

• Dual secondary resonators

• Retains factory PSE valve control

• Meaningful quieter mode

• Approximately 20 lbs

• Approximately 3 lbs lighter than stock

• Best suited to owners wanting increased sound with everyday flexibility

SOUL Non-Valved X-Pipe

• Permanently open 3-inch exhaust path

• No valves-closed secondary route

• Greater constant exhaust presence

• Lighter and simpler construction

• Greater weight savings

• Better suited to owners prioritizing maximum sound and simplicity

For a street-driven 991.2 Carrera, the Valved Exhaust provides considerably more control over when the additional exhaust volume is present.

EXHAUST TIPS:

The Valved Exhaust System is sold as a single rear-exhaust configuration with no exhaust-tip selection on the SOUL product page.

SOUL offers separate bolt-on exhaust-tip upgrades for the 991.2 Carrera with PSE, allowing the visible tip configuration to be selected independently from the rear exhaust.

This keeps the Valved Exhaust itself to a single SKU.

EMISSIONS:

The SOUL Valved Exhaust System replaces the rear muffler section downstream of the vehicle's catalytic converters and oxygen sensors.

When installed with factory upstream components, it does not remove or modify the catalytic converters.

Emissions compliance can change if the system is combined with separate Sport Catalytic Converters, Cat Bypass Pipes, or other emissions-related components.
