3" Stainless Steel Downpipe with Catalytic Converter

The CTS Turbo High Flow CAT Downpipe is engineered to boost performance for select VW and Audi 2.0T AWD models. Constructed from premium 3" T304 seamless stainless steel tubing with 100% TIG welded seams, this downpipe is built for longevity and resistance to cracking and decay. It features a 200-cell metallic race catalytic converter, T304 stainless steel flanges and O2 bungs, and includes installation hardware and stainless steel clamps. A notable feature is the removable 60mm reducer, designed to interface with the factory exhaust sleeve clamp. The 3" diameter piping facilitates smoother exhaust gas flow, enhancing turbo spool-up and increasing both peak power and torque across the entire powerband. This downpipe is specifically designed for the 2012-2013 VW MK6 Golf R 2.0T, 2006-2013 Audi MK2 TT Quattro 2.0T, 2006-2013 Audi MK2 TTS Quattro 2.0T, 2006-2013 Audi 8P A3 Quattro 2.0T, and 2006-2013 Audi 8P S3 Quattro 2.0T. **Important Considerations:** * This product is sold for competition use and is not legal for use in highway or street vehicles. * Stage 2 software is required to avoid a check engine light. * Professional installation is recommended.
