The STM 2-Piece 3.5" Downpipe is the perfect addition to your RS3 or TTRS! Beautifully crafted in the USA, this stainless steel downpipe features a billet v-band flange to mate perfectly to your factory turbo, full 3.5" construction then merged into two 2.5" outlets to mate up to your stock or factory-style cat-back exhaust.
Three oxygen sensor bungs are included for the factory front and rear sensors as well as an extra bung if you choose to run an aftermarket wideband gauge. Utilizes factory exhaust hangers. This system re-uses your factory Audi v-band turbo to downpipe clamp and cat-back exhaust clamps.
