304 Stainless Steel Test Pipes

The Canadian Auto Performance test pipes are engineered as a premium exhaust upgrade for Audi 3.0T Supercharged V6 (3.0 TFSI) engines, replacing restrictive factory catalytic converters to maximize exhaust flow and power. Constructed from the thickest 304 stainless steel available and featuring a one-piece, 100% mandrel-bent and TIG-welded design, these test pipes minimize welds to enhance durability and withstand high exhaust gas temperatures. The bolt-on installation is designed for compatibility with both OEM and CAP 2.5" downpipes, promising improved exhaust flow and a more aggressive sound. Available in regular, ceramic-coated, and heat-shielded versions, these test pipes offer performance benefits including increased horsepower and torque, estimated at 10-40 HP depending on the application, and reduced exhaust temperatures for improved engine reliability. The ceramic-coated and heat-shielded options further help in reducing heat and minimizing exhaust rasp often associated with catless systems. Owners report sustained performance gains and no reported cracking issues with the V3 design, which includes an industry-first 3-bracket system to mitigate vibrations. It is recommended to replace gaskets and bolts during installation. Removal of factory catalytic converters will trigger a check engine light; software tuning is advised to optimize power gains. The manufacturer also recommends using their 180 Degree / Straight O2 Spacers, offering a discount with test pipe purchases. This product is intended for Racing Competition use only and is not street-legal or CARB compliant. Explicitly, these test pipes do NOT fit Audi Q7 models and do NOT fit the 2005-2011 C6 Audi A6. Compatibility extends to numerous Audi models including B8/B8.5 S4/S5, C7/C7.5 S6, C8 S6, and various A6, A7, Q5, and SQ5 generations from approximately 2008-2024, but specific fitment should always be verified.
