Unleash Your Car's True Potential

Designed with a 3.0” stainless steel collector this system with its straight-through design allows you to unleash the car’s true potential. This performance pipe replaces the factory exhaust catalyst and bolts up to your existing manifold, factory rear muffler, or Active Autowerke Gen 3 Signature High Flow Exhaust. All hanger placements precisely follow factory-mounting points. The exhaust tone produces is a sporty mellow tone at low rpms, giving way to a distinct racy growl at wide-open throttle. Weighing in at just 28lbs, this performance-enhancer also shaves some 30% off the stock catalyst it replaces.
