This 034Motorsport high-flow downpipe replaces the restrictive factory catalytic converter on the 2005.5-2008 B7 Audi A4 2.0T FSI, in quattro or FWD form with manual, Tiptronic or CVT transmissions. It is built from full 3" stainless steel tubing with a 250-cell stainless steel matrix catalytic converter, TIG welded in-house, with precision flanges that resist warping and factory-correct hanger and oxygen sensor locations. 034Motorsport says it quickens turbo spool and has measured gains of over +33 WHP and +27 WTQ on its dyno with stock turbo tunes.
