For S4 & S5 owners looking to fine tune the sound even more, we offer AWE Tuning Resonated and Non-Resonated Downpipes. Their Resonated Downpipes (strongly recommended for S-tronic cars) feature resonators larger than the stock units in order to produce a mellow sound volume. These optional Non-Resonated downpipes are suited for owners seeking a "loud" and aggressive sounding system. Both our Resonated and Non-Resonated Downpipes feature larger than stock tubing diameter.
Sound levels from quietest to loudest:
Highlights of the Downpipes:
None of the components of AWE's B8 downpipes affect or alter any of the emissions devices on the vehicle, and therefore are legal for street use.
As with all A.W.E. Tuning exhaust products, each TIG weld is hand finished internally, only butt-welded junctions are used, and flange openings are size matched to their ports, all to produce the smoothest flow possible. It is this intensive attention to detail that sets A.W.E. Tuning exhaust products heads and shoulders above the rest.
AWE's exhaust systems are hand built works of art, are award winning, and are what your Audi deserves.
