DEVELOPMENT:  Our goal was to offer a valved exhaust package that delivers a unique and aggressive exhaust note without sacrificing a refined cabin experience – from mild to wild at the press of a button. An upgraded downpipe greatly enhances the character of the car, but without a proper rear exhaust it can introduce undesirable drone during normal driving conditions, especially around 3,000 RPM. It is easy to increase the volume of the 718, but a challenge to bring out a more aggressive note while making the flat four sound distinctly Porsche which is a common complaint. The turbo and large amount of sound deadening in the 718 do a great job of keeping the cabin calm, but raising the volume to compensate can bring out negative notes in the exhaust such as rasp and drone. We applied the same design principles as our renowned Valved Exhaust line for previous Boxster / Cayman generations to deliver a refined increase in sound that pairs well with the upgraded, freer flowing downpipe to yield a mature exhaust note without ever being overbearing. This is a superior option for cars not equipped with the Porsche Sport Exhaust from the factory. For the downpipe, smooth mandrel bent piping ranging from 90mm down to 55mm upon exit encourages better throttle response, turbo sound, and an overall more exciting exhaust note.

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. Each downpipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked.


SOUND: Experience refined aggression! The overall exhaust note is much sharper and the turbos make themselves known. With valves closed, you can carry on a phone conversation on the highway without any intrusion from the exhaust. The exhaust offers a respectable level of snarling and crackling while effectively minimizing drone at all RPM and throttle loads. Sport mode unleashes an increase in crackles and burbles.

VALVE OPERATION: A valve controller is included with every system and is required for non-PSE cars. PSE equipped cars will retain full factory functionality by using the factory vacuum lines. The valve controller is optional for PSE equipped cars and allows full valve control at all times. Valve functionality can be controlled by the factory PSE button, included valve controller fobs, and with HomeLink buttons.

TIPS: Choose from several different tip styles and finishes. Single wall tips have around a half inch of depth adjustment to allow for the tips to be sunk in to just show the logo at their deepest and pulled out more if desired. Double wall chrome tips are longer in length by 1″ and protrude from the bumper aggressively.  Logo customization is available, please contact us.


BOLT ON AND GO:  Each component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.

CHECK ENGINE LIGHT?:  This product may trigger a check engine light due to removal of the factory catalytic converter.

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.
