AWE Tuning Audi B8 3.0T Non-Resonated Downpipes for S4 / S5

AWE offers Resonated and Non-Resonated Downpipes. The Resonated Downpipes (strongly recommended for S-tronic cars) feature resonators larger than the stock units in order to produce a mellow sound volume. AWE's optional Non-Resonated downpipes, which is what you're lookin' at, are suited for owners seeking a "loud" and aggressive sounding system. Both our Resonated and Non-Resonated Downpipes feature larger than stock tubing diameter. These post-cat downpipes replace the factory resonated downpipes, and pair directly to existing AWE exhausts. They work with the factory exhaust, too, if you're looking to keep it stock in the back. Note: In limited cases, the factory downpipes have been known to emit minor rattling noises when paired with the AWE S4 3.0T exhaust system. The possibility of rattling is eliminated with the addition of an AWE downpipe.Installation InstructionsThis Part Fits: Year Make Model Submodel 2010-2013 Audi S4 Base 2014-2016 Audi S4 Premium Plus 2014-2016 Audi S4 Prestige 2013,2017 Audi S5 Base 2010-2013 Audi S5 Cabriolet 2014-2016 Audi S5 Premium Plus 2014-2016 Audi S5 Prestige
