SLE Catless Test Pipes – Audi 3.0T Supercharged (S4 / S5 / Q5 / SQ5 B8/B8.5, A6 C7, A7 C7, A8 D4) 2010–2018

Description:
The SLE Catless Test Pipes are a high-performance upgrade for Audi’s 3.0T TFSI supercharged V6, designed to reduce backpressure, improve throttle response, and unleash a louder, more aggressive exhaust tone. By eliminating the factory catalytic converters, these test pipes deliver maximum exhaust flow and a noticeable bump in performance — especially on tuned vehicles.

Constructed from T304 stainless steel with TIG-welded and back-purged seams, these pipes are built to withstand the demands of high-boost setups. Each kit includes new gaskets and mounting hardware for a smooth, bolt-on installation.

Perfect for enthusiasts running stock or Stage 2 setups, this upgrade not only enhances power but brings out the signature whine of Audi’s supercharged 3.0T.
