Copper gaskets should not be reused
SOUL confirms the four-piece contents, OEM gasket references, approximately 1 mm copper construction, 2013–2016 981 fitment, and specifies that the copper gaskets should not be reused.
Exhaust gaskets should be replaced whenever the sealing surfaces have been disturbed or when existing gaskets show signs of wear, damage, or leakage.
SOUL specifically states that these copper gaskets are single-use components and should not be reused after installation.
The SOUL Race Exhaust System is engineered for Porsche 981 Boxster and Cayman owners who prioritize maximum sound, reduced weight, durability, and track-focused performance. Unlike SOUL's street-oriented Performance and Valved Exhaust systems, the Race Exhaust is built specifically around the demands of sustained high-performance driving, with minimal emphasis on sound attenuation and maximum emphasis on simplicity and strength.
Full 2.5-inch over-axle piping provides a free-flowing exhaust path while maintaining clearance around the axles and sway-bar end links, including on heavily modified or lowered vehicles. The system uses dedicated transmission-mounted support hardware rather than relying solely on conventional welded exhaust hangers, helping reduce stress on the exhaust assembly during aggressive track use.
SOUL developed a bespoke mounting system with separate configurations for Manual and PDK transmissions. The forward piping attaches to the transmission brace using heavy-duty Mikalor band clamps, while additional rubber vibration dampeners support the over-axle piping and help isolate movement and vibration. The mounting system itself saves more than 5 lbs compared with the factory mounting hardware.
The complete system weighs approximately 30 lbs, compared with approximately 44 lbs for the factory non-PSE exhaust and 48 lbs for the factory PSE system with mounting brackets, providing weight savings of approximately 14–18 lbs depending on the original exhaust configuration.
This is an intentionally aggressive exhaust system. SOUL specifically designed it for track use and warns that it is very loud, with cabin drone still present despite the resonated configuration. For owners looking for maximum flat-six sound and a purpose-built track exhaust, the Race Exhaust provides the most uncompromising option in SOUL's standard 981 lineup.

The SOUL Race Exhaust System was developed primarily for track performance rather than sound attenuation.
SOUL describes the system as very loud and notes that cabin drone will remain present even with resonators. Pairing the Race Exhaust with aftermarket headers will further increase overall volume, and SOUL specifically does not recommend running this combination on the street.
For owners looking for a more refined exhaust experience with the ability to reduce volume when desired, the SOUL Valved Exhaust System is the more street-oriented alternative.
The SOUL Race Exhaust is the most track-focused option in the standard 981 exhaust lineup. Its lightweight mounting architecture, full 2.5-inch piping, and aggressive sound profile prioritize durability, weight reduction, and maximum exhaust presence.
The SOUL Performance Exhaust is intended for drivers who still want a consistently aggressive non-valved exhaust but prefer greater sound attenuation and street usability through conventional mufflers.
For dedicated track cars or owners prioritizing maximum sound and reduced weight, the Race Exhaust is the more purpose-built configuration. For a primarily street-driven 981, the Performance Exhaust provides a more controlled compromise.
This DasMotoring listing includes SOUL Slash-Cut exhaust tips in Signature Satin.

The SOUL Performance Exhaust System is designed for Porsche 981 Boxster and Cayman owners who want a more aggressive naturally aspirated flat-six exhaust note without the complexity of a valved system. Developed as a lighter, valveless alternative to SOUL's Valved Exhaust, the Performance Exhaust delivers its more aggressive sound at all times while using high-quality mufflers to control unwanted drone and rasp.
SOUL specifically developed the system to provide substantially more volume than the factory Porsche Sport Exhaust with its valves open while maintaining a refined exhaust character. The mufflers help produce a fuller, more robust tone rather than simply increasing overall volume, making the system suitable for spirited street driving as well as track use where sound quality and exhaust flow are priorities.
The system uses 2.5-inch OD over-axle piping constructed from mandrel-bent T304L stainless steel. Reinforced muffler casings and durable sound-absorbing material are designed to withstand extended street and track use without degrading over time.
For owners pairing the exhaust with aftermarket headers, the Performance Exhaust offers an aggressive overall sound while retaining mufflers to help control excessive rasp and cabin resonance. Unlike the SOUL Valved Exhaust System, there are no exhaust valves or selectable sound modes—the system provides its full exhaust character whenever the car is running.

The SOUL Performance Exhaust is a fixed, non-valved exhaust system.
Vehicles originally equipped with Porsche Sport Exhaust can use the SOUL Performance Exhaust, but the factory exhaust-valve functionality is no longer used after installation. The exhaust will maintain its more aggressive sound at all times rather than switching between quiet and loud modes.
For owners who want to retain selectable exhaust volume and valve functionality, the SOUL Valved Exhaust System is the more appropriate configuration.
This DasMotoring listing includes SOUL Straight-Cut Single-Wall exhaust tips in Signature Satin.
To keep ordering simple, alternate tip finishes and styles are not offered through the standard product options. If you would like a different SOUL tip configuration, contact DasMotoring before ordering and we can confirm availability and pricing.
SOUL also offers alternate stainless steel and titanium tip styles and finishes by special request. Titanium single-wall tips save nearly one pound compared with stainless steel tips.
The SOUL Performance Exhaust uses a fixed, non-valved configuration for drivers who want a consistently aggressive exhaust note, reduced complexity, and high exhaust flow.
The SOUL Valved Exhaust System adds controllable exhaust valves, allowing the driver to significantly reduce exhaust volume when desired while retaining an aggressive flat-six sound with the valves open.
For owners who want the car to sound aggressive at all times and do not need selectable exhaust modes, the Performance Exhaust provides the simpler solution. For frequent highway driving, early-morning use, or owners who want the ability to quiet the car on demand, the Valved Exhaust provides greater flexibility.
This listing is intended for standard 981 Boxster and Cayman Base, S, and GTS models.
The 981 Cayman GT4, Boxster Spyder, and GT4 Clubsport use a separate SOUL Performance Exhaust System designed specifically for those vehicles. SOUL maintains a distinct GT4 / Spyder / Clubsport exhaust application.
The SOUL Valved Exhaust System is designed for Porsche 981 Boxster and Cayman owners who want to bring out significantly more of the naturally aspirated flat-six character while retaining the ability to quiet the car when desired. Rather than simply increasing volume, the system uses two distinct exhaust paths to provide a refined, controlled sound with the valves closed and a dramatically more aggressive motorsport-inspired tone with the valves open.
With the valves closed, exhaust gases are routed through SOUL's packed mufflers, which are specifically designed to minimize cabin drone while maintaining a refined, sporty exhaust note. This makes the system well suited for highway cruising, longer trips, early-morning starts, and everyday street use.
Open the valves and exhaust gases are allowed to flow through large 2.5-inch piping, substantially increasing volume and allowing more of the 981's naturally aspirated flat-six sound to come through. Perforations within the system keep the mufflers acoustically connected to the exhaust path, helping create a fuller and more robust tone rather than simply making the car louder.
For vehicles equipped with factory Porsche Sport Exhaust (PSE), the SOUL system can retain factory valve operation using the existing exhaust controls. Vehicles without PSE use the included SOUL valve controller. The controller can also provide direct manual valve override on PSE-equipped vehicles, giving the driver greater control over when the exhaust valves are open or closed.
The result is a versatile exhaust system that can remain refined and comfortable when desired while transforming the sound and character of the 981 when the valves are opened.

The SOUL Long Tube Street Headers are designed for Porsche 981 Boxster and Cayman owners looking to improve exhaust flow, throttle response, and naturally aspirated flat-six sound while retaining catalytic converters. Combining long-tube runner geometry with large, free-flowing catalysts, the system provides a more performance-oriented exhaust path without moving to a fully catless configuration.
SOUL developed the headers specifically around the 981 platform, using 2-inch primary runners and appropriately sized collectors to improve exhaust flow. The design was optimized around the 3.4L flat-six while also providing meaningful improvements for the 2.7L engine.
Each header incorporates a SOUL-designed, U.S.-produced 300-cell catalytic converter featuring a custom-specified precious-metal catalyst coating and triple metal-matrix core. This allows the Street Headers to reduce restriction compared with the factory assemblies while retaining catalytic converters and, according to SOUL, operating without triggering a check engine light.
Port-matched flanges, smooth-radius primary tubing, long-tube runner geometry, and performance-oriented collectors work together to create a smoother exhaust path from the cylinder heads through the catalysts. The result is a freer-revving, more responsive flat-six with increased exhaust character while retaining a more street-oriented configuration than SOUL's catless Competition Headers.

Backed by SOUL Performance Products' Lifetime Warranty for both street and track use
The SOUL Long Tube Street Headers retain 300-cell high-flow catalytic converters and are designed for owners looking for improved exhaust flow, response, and flat-six sound while maintaining a catted exhaust configuration.
The SOUL Competition Headers eliminate the catalytic converters entirely for a less restrictive exhaust path, greater weight reduction, and a substantially more aggressive exhaust note.
For owners who primarily drive their 981 on the street and want a significant exhaust upgrade without moving to a fully catless configuration, the Long Tube Street Headers provide the more refined solution.
SOUL specifically designed the 300-cell catalytic converters and catalyst coating used in these headers to provide increased exhaust flow without triggering a check engine light under normal operating conditions.
An ECU tune is not required for installation. However, an appropriate performance calibration may allow the engine to take additional advantage of the improved exhaust flow when combined with other modifications.
A SOUL copper header gasket set can be added for customers replacing worn factory gaskets or who prefer a reusable, high-quality gasket solution.
The copper gasket set is available as a $65 option with the headers.
These headers retain catalytic converters; however, the product is not CARB certified and may not be legal for use on emissions-controlled vehicles. SOUL identifies the product as intended for off-road use.
Customers are responsible for ensuring compliance with all applicable local, state, and federal regulations before installation or use.
The SOUL Competition Headers transform one of the most restrictive sections of the Porsche 981 Boxster and Cayman exhaust system. Replacing the heavy factory manifolds and catalytic converters with a free-flowing, catless header design reduces restriction, removes approximately 11 lbs from the vehicle, and allows substantially more of the naturally aspirated flat-six character to come through.
SOUL developed these headers specifically for the 981 platform, using 2-inch primary runners and properly sized collectors to improve exhaust flow and engine response. While the system was optimized around the 3.4L engine found in the Cayman S and Boxster S, SOUL designed the same architecture to provide meaningful improvements on the 2.7L engine as well.
Port-matched flanges, smooth-radius primary tubing, and performance-oriented collectors work together to improve exhaust flow through the complete header assembly. Removing the factory catalytic converters also produces a considerably more aggressive exhaust note and allows the engine to respond more freely throughout the rev range.
For owners looking to extract more sound and performance from a naturally aspirated 981 while significantly reducing exhaust restriction and weight, the Competition Headers are one of the most substantial exhaust upgrades available for the platform.

The SOUL Competition Headers remove the factory catalytic converters and may trigger a check engine light as a result.
SOUL recommends an appropriate ECU calibration for vehicles using these headers to address catalyst-related fault codes. ECU tuning may also allow the engine to better take advantage of the increased exhaust flow provided by the catless header configuration.
Optional O2 sensor spacers are available, but they should not be considered a guaranteed method of preventing catalyst-efficiency fault codes.
Optional O2 sensor spacers are available for customers who would like them included with the Competition Headers.
O2 spacers reposition the downstream oxygen sensors farther from the direct exhaust stream and may reduce the likelihood of catalyst-efficiency fault codes in some applications. Results can vary by vehicle and calibration, and DasMotoring does not guarantee that O2 spacers will prevent a check engine light.
The SOUL Competition Headers remove the factory catalytic converters and are not CARB certified. SOUL identifies this product as intended for off-road use due to removal of the factory catalytic converters.
