Description
Unlock the full performance potential of your Audi 2.0T with the Canadian Auto Performance High Flow Catted Downpipe for the B9 platform. Engineered with precision and built to the highest standards, this downpipe is a significant upgrade over the restrictive OEM catalytic converter, designed to maximize exhaust flow, improve power delivery, and enhance the exhaust tone of your Audi.
Crafted from premium 304 stainless steel and TIG welded for superior durability, the CAP downpipe is a result of the same expertise behind our best-selling B8 S4 test pipes — known for unmatched reliability with over 500 installations and zero failures. Now, that same level of engineering excellence is available for B9 2.0T owners who demand performance without compromise.
By replacing the factory downpipe and restrictive catalytic converter, this high-flow unit reduces back pressure, minimizes turbo lag, and significantly increases horsepower and torque when paired with a proper Stage 2 ECU tune. The improved exhaust tone delivers a more aggressive and refined sound that complements the car’s sporty nature without introducing unwanted drone.
This unit is a bolt-on installation and includes high-quality 304 stainless steel gaskets. Please note this product is intended for off-road and racing use only and is not emissions compliant.
