Increase throttle response, power, and add a refined amount of exhaust note to your 958 Cayenne without triggering a check engine light. DETAILS: + Fits all Porsche 958 / 958.2 Cayennes (2011+) + Weighs 9 lbs / 4 kg less than factory exhaust components (17 lbs vs 8 lbs) + Designed and built in-house at our Willow Grove, PA facility 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. 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. Smooth mandrel bends, thick flanges, and back purged welds all ensure product longevity. Each set of cat bypass pipes is 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. CHECK ENGINE LIGHT?: This product should not trigger a check engine light as the secondary catalytic converters are unmonitored by the ECU NOTE This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only
