Show original supplier description
The CTS Turbo 3" High Flow Cat Pipe is engineered to enhance the performance of your 2006-2008 Audi A4 2.0T. Constructed from T304 stainless steel with smooth mandrel bends and hand TIG welding, this cat pipe is designed to seamlessly replace the factory catalytic converter, located immediately after the turbocharger. Its 3" piping and near 4" flare that tapers to 3" optimize exhaust flow from the turbocharger. This high-flow cat pipe offers substantial power gains, improved exhaust flow, and a more aggressive exhaust note. It comes equipped with two O2 sensor bungs, and a third bung for wideband sensor logging is also included. Installation hardware is also provided. **Important Fitment Information:** This cat pipe is designed for 2006-2008 Audi A4 2.0T models with manual or automatic transmissions. It is exclusively for Left-Hand Drive (LHD) vehicles. It does NOT fit CVT or front-wheel drive (FWD) cars. Proper tuning software, such as a stage 2 software upgrade, is required to prevent a Check Engine Light (CEL) after installation.
