DEVELOPMENT AND TESTING: In order to to prevent the 987.2 from eclipsing the performance of the 911, Porsche fits a restrictive and bulky exhaust system robbing the Cayman / Boxster of its natural power and sound – and that we can’t abide. We developed the Valved Exhaust on our own Project 987.2 Cayman S to ensure the delta between exhaust modes was noticeable and refined, even when paired with aftermarket headers. During dyno testing on a Dynojet, we experienced max gains of 8 whp and 11 ft-lbs of torque at 4,100 RPM when paired with our Long Tube Street Headers on the SOUL project Cayman S. This system is currently run by our daily driven Cayman S and track tested consistently by our Project Cayman R. Aftermarket Boxster/ Cayman exhaust hangers / supports are often prone to cracking and failing – SOUL fortified brackets prevent any damage during extended street use and track days.
CONSTRUCTION: Each system is made from mandrel bent T304L stainless steel tubing (featuring 2.5″ OD over axle pipes) and features mufflers with fortified casings in the interest of durability. With valves closed the exhaust gasses are routed into the SOUL muffler, which is packed with high quality sound deadening material designed to withstand abuse and not blow out over time. The mufflers are incredibly effective at minimizing drone. Exhaust gasses make their way through the muffler and out through perforations into the outer piping. With valves open, exhaust gasses are now free to exit out through large 2.5″ piping while perforations allow exhaust gasses to “talk” with the muffler, encouraging a fuller, more robust tone. Choose from a variety of 321 stainless exhaust tips in different styles and finishes – or contact us to customize your own set! Titanium single wall tips are also available and save nearly a pound of weight over stainless steel tips!
BOLT ON AND GO: Each exhaust is tested in a fixture to ensure perfect fitment then foam packed to arrive in perfect condition. New high grade hardware is included for the header to exhaust flanges. Thorough installation instructions are included in the box for a straightforward install that can be performed by 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.

Had this valved exhaust fitted not long ago and it has transformed the car into the beast i always wanted. The sound build up is intoxicating! Starting from a deep gurgle to a high end throaty wail that begs for more.. Very Pleased with it. The chaps at soul were incredibly helpful and responsive!
I heard about SOUL from a friend who owns a 981 and has their valved exhaust and headers on his car. I absolutely loved how his car sounded and knew I wanted to get their exhaust on my car as well. I spent countless hours listening to exhaust videos on YouTube beforehand and SOUL by far was the best sounding system! I knew even before I bought the car that I wanted SOUL’s system on my car. I’m absolutely in love with the results!

I’m extremely impressed with the sound and the throttle response my Porsche Cayman got from the soul performance exhaust. Definitely awakens the car and sounds amazing on rev match downshifts. I was also super impressed by the customer service I was getting from the staff and the updates on my exhaust in transit. Definitely would recommend to anyone looking for high quality exhaust and crisp sound.

I went from a stock non PSE to a valved catback from Soul last month on my 09. It gives it the sound these cars should have. The stock non PSE car sound is depressing. As far as performance the catback alone is not gonna give you much but the tone and the feel adds to the great driving experience. I went with the valve system because I plan to go catless headers and a tune next Spring and want the valve to minimize drone with the full setup.
