DEVELOPMENT AND TESTING: We could not curb our curiosity of what a 991.2 C4S would sound like with a true straight pipe exhaust. Using 3” mandrel bent tubing straight out of the turbos to the rear of the car and fitting single wall turn downs, this exhaust system is radical, simple, and ferocious sounding. We approached AWE Tuning about testing our development car at their facility for third party dyno results. We experienced gains of 17 whp and 14 ft-lbs of torque at 6,500 RPM as tested on a 2017 Carrera 4S with no other mods. Peak power was up by 12 whp and 12 ft-lbs. Much greater gains can be expected from the freer flowing exhaust components when paired with a tune. During testing we experienced no CEL, but cannot guarantee the same results on all cars as all cars are different and unique.
CONSTRUCTION: Each exhaust is assembled out of thick wall .065″ T304L stainless steel and 321 stainless for the tips and rigorously quality checked in-house. Smooth mandrel bends and thick flanges precision cut by a waterjet ensure product longevity. It was also important that we retain use of the factory heat shields as to not heat soak the components around the turbos.
BOLT ON AND GO: Each exhaust is tested in a fixture to ensure perfect fitment then foam packed to arrive in perfect condition. Hardware and thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
HJS CATALYSTS: Optional HJS HD 200 cell catalytic converters can prevent a check engine light. The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here!
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 that you may have.
