DEVELOPMENT: We wanted to design a valved exhaust that would offer the ability to go from “Cruising Sunday to Track Day” at the press of a button with the default setting to be valves closed for a more refined startup experience. Following the extreme effectiveness of the Porsche mufflers used in our 987 / 981 exhausts to combat drone, we’ve applied the same design principles to a bespoke muffler for the 997 Carrera.
SOUND: The design of our exhaust channels exhaust gases through our bespoke mufflers for a sophisticated and sporty sound that is unmistakably Porsche with valves closed, and this is the default operation setting. With valves open, you’re getting a CUP–inspired straight pipe sound. With valves closed during cruising, there is no drone — even with aftermarket catalytic converters! Due to the aggressive, free–flowing nature of the valves–open mode, the volume is loud when paired with aftermarket catalytic converters or catless replacement pipes.
CONSTRUCTION: Each system is made in-house by our fabrication team from mandrel bent .060″ wall T304L stainless steel tubing, bespoke SOUL mufflers, and laser cut brackets – with well over 15 man hours invested in each set of Porsche valved exhaust components to make sure they are perfect.
BOLT ON AND GO: Each exhaust is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment. Every set is rigorously quality-checked prior to shipping.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components for your Porsche 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 questions or issues that you may have.
