- No check engine light on North American cars
- Weighs up to 29.9 lbs / 13.5 kg less than factory exhaust components (27.5 lbs Non-Res vs 30.85 lbs Resonated vs 57.4 lb Factory)
- T304L stainless steel
- Re-uses factory tips
DEVELOPMENT: Would it be a GT4 exhaust suite without upgrades for the track enthusiasts? We redesigned the entire exhaust aft of the headers for maximum flow. The factory dual exit/entry flanges connecting the over axle pipes to the PSE muffler limits the piping diameter to 2.25”. The SOUL Race Exhaust is optimized into a single 2.5″ flow path on either side with accommodations to mount factory style tips. Great care was made to mind clearances for hard use on and off the track, expect no issues with our mandrel bent piping. The longer piping routing also helps noticeably smooth out the exhaust sound while the slight blending of the X gives the car a higher pitched sound more akin to the previous 981 generation we’ve come to know and love. Durable race resonators add a more refined note to the aggressive exhaust note while slightly reducing drone. A non-resonated version is option for those looking for maximum weight reduction and sound.
CONSTRUCTION: Each system is assembled in house in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity. Water jet cut flanges are made to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. We fabricate these over axle pipes using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.
BOLT ON AND GO: Every component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition. New high grade hardware and four OEM Porsche gaskets are included for installation.
