DEVELOPMENT: The 958 Cayenne comes with two sets of catalytic converters from the factory for a total of four restrictive units – upgrading them is a common, cost effective modification. Our goal was to provide a cost effective upgrade while incorporating quality wherever possible. The OEM pipes were first scanned with a ROMER arm, and a bend profile was developed to produce smooth, large radius bends from thick US sourced T304L stainless steel – mandrel bent to strict ISO 9001:2015 quality standards. You’ll be treated to a fuller exhaust sound without a significant increase in drone. Throttle response and overall drivability is increased.
CONSTRUCTION: Each set is assembled out of 2.5″ OD, thick-wall .065″ T304L stainless steel and rigorously quality checked in-house. Every cat bypass pipe is built from smooth mandrel bends, thick water-jet cut flanges, and laser cut brackets. Back purged welds ensure proper penetration and overall product longevity. The final pipes are tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition. New hardware is included for the header flanges.
