3-Inch Stainless Steel Cat-Back Downpipe

The CTS Turbo 3″ Stainless Steel downpipe, featuring a high-flow catalytic converter, is engineered for Audi/VW 2.0T FSI and 2.0TSI transverse engines. It addresses the performance limitations of the factory downpipe, which can restrict exhaust flow and negatively impact horsepower, particularly after ECU tuning. This downpipe is constructed from T304 seamless stainless steel tubing and T304 stainless steel flanges, with 100% TIG welding for durability. It includes a 200-cell metal high-flow catalytic converter, three oxygen sensor bungs for compatibility, and stainless steel clamps. The modular design and a removable 60mm reducer facilitate straightforward installation. It is compatible with factory or aftermarket cat-back exhaust systems but requires the factory sleeve clamp (not included). An optional install kit with a gasket and four copper lock nuts is available. Key compatibility includes BPY, BWA, CBFA, and CCTA engines. The downpipe is designed for FWD models of the Audi A3 8P (2005-2013), Audi TT Mk2 (2008-2015), VW CC (2009-2017), VW Golf/GTI Mk5 (2006-2009), VW Golf/GTI Mk6 (2010-2014), VW Mk5 (2006-2010), VW Mk6 (2011-2014), and VW Passat B6 (2006-2010).
