Porsche 981 Boxster / Cayman MANUAL TRANSMISSION -
SOUL Race Exhaust System.
SOUL’s Race Exhaust System is designed for aggressive track use and built around maximum durability, lightness, and performance.
• Fits all Porsche 981 Cayman / Boxster vehicles (2013-2016) MANUAL TRANSMISSION, with factory or SOUL headers (differences in tolerances from other manufacturers can create issues with over axle pipe clearance)
• Designed and built in-house at our Willow Grove, PA facility
• System weighs approximately up to 18 lbs / 8.1 kg less than factory exhaust non-PSE components ( 30 lbs vs 44 lbs non-PSE / 48 PSE with mounting brackets included)
• All Soul Performance Products components are backed by a renowned Lifetime Warranty for both street and track use
DEVELOPMENT::
Our mission was to engineer a lightweight, durable, and cost-effective race exhaust system for the 981 Boxster and Cayman—one that delivers proven performance, reliability, and accessibility for serious track enthusiasts. By collaborating with respected shops, technicians, and seasoned drivers who have conducted their own independent testing over the years—including special thanks to Bryan Schute at Speed Sport Tuning and the teams at LN Engineering / BRS—we developed a track-bred system designed to meet the demands of competitive driving.
PIPING:
The system features full 2.5” over-axle piping, carefully profiled to provide sufficient clearance for axles and sway bar end links—even on aggressively lowered or heavily modified vehicles.
BESPOKE BRACKETS & MOUNTS:
Traditional welded hangers and brackets are prone to failure under the rigors of racing—a failure that can end a track day instantly. To solve this, SOUL designed a reinforced mounting solution that sheds over 5 lbs compared to the OEM setup, while remaining modular and easy to repair or replace after a track incident.
The forward piping connects to a custom SOUL transmission mounting brace—engineered for both manual and PDK models—via heavy-duty Mikalor band clamps. Additional rubber vibration dampeners support the over-axle piping, minimizing stress from flex and vibration across the system to ensure long-term durability under extreme use.
CONSTRUCTION:
Each system is handcrafted in-house by our skilled fabrication team using mandrel-bent .065″ wall, 2.5″ diameter T304L stainless steel tubing. Brackets are laser-cut, press brake-formed, and TIG welded for maximum strength, while all welds are back-purged to ensure long-term durability under the most extreme racing conditions.
SOUND:
This system is designed with track performance as the priority, not sound suppression. It is extremely loud, and even with resonators, some drone will be present. We do not recommend pairing this exhaust with aftermarket headers for street use. At wide-open throttle, however, the sound is nothing short of exhilarating—raw, aggressive, and unmistakably motorsport. For a more balanced option suited to daily driving, we suggest our Valved Exhaust System.
BOLT-ON INSTALLATION:
Every exhaust is rigorously quality-checked and fixture-tested to guarantee perfect fitment. Systems are securely foam-packed for safe delivery and include all-new high-grade hardware for the header-to-exhaust flanges. Thorough instructions are provided, making installation straightforward for most DIY enthusiasts.
LIFETIME WARRANTY:
Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
