DEVELOPMENT AND TESTING: We selected 3″ diameter piping to maximize exhaust flow and the sound of the turbos spooling – and oh do you hear them now. We designed our Cat Bypass Pipes to have a straight through exhaust path with valves open in pursuit of maximum exhaust flow and power – if you’re deleting catalysts that is surely your focus! We’ve positioned the secondary tube into the Porsche Sport Exhaust where it is to keep the valves closed tone civil and refined while still receiving ample exhaust flow. It was also important that we retain use of the factory heat shields as to not heat soak the components around the turbos.
POWER: We approached AWE Tuning about testing our development car at their state of the R&D facility for third party dyno results. We experienced max gains of 20 whp and 21 ft-lbs of torque at 5,800 RPM as tested on a 2017 Carrera 4S with no other mods. Peak power was up by 10 whp and 14 ft-lbs. BoostAddict upped power in their Carrera from a baseline of 344 whp and 326 ft-lbs of torque to 455 whp and 448 lb-ft of torque with our Cat Bypass Pipes and race gas tune.
CONSTRUCTION: Each set is assembled out of thick wall .065″ T304L stainless steel and rigorously quality checked in-house. Smooth mandrel bends and thick flanges ensure product longevity.
BOLT ON AND GO: Each product is tested in a fixture to ensure perfect fitment 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.
