For S4 owners looking to fine tune the sound even more, we offer our Resonated and Non-Resonated Downpipes. Our Resonated Downpipes (strongly recommended for S-tronic cars) feature resonators larger than the stock units in order to produce a mellow sound...
Sound levels from quietest to loudest:
AWE Tuning exhaust with AWE Tuning resonated downpipes (highly recommended for all S-tronic S4s)
