About the downpipes
We offer our Non-Resonated Downpipes.
- Our Non-Resonated Downpipes are suited for owners seeking the loudest we have to offer in the S4 line up.
Non-Resonated Downpipes feature larger than stock tubing diameter.
Downpipe + Exhaust packages offer the most cost-effective solution.
Downpipe installation tip
Installing downpipes on these cars is arduous given the placement of the factory bolts. We had so much trouble that we made an AWE Tuning-grade tool to make it easier. If you're planning an install, our Downpipe Removal Tool is a must have.

None of the components of our S4 exhaust system affect or alter any of the emissions devices on the vehicle, and therefore are legal for street use.
As with all AWE Tuning ® exhaust products, each TIG weld is hand finished internally, 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 AWE Tuning ® exhaust products heads and shoulders above the rest.
Note: In limited cases, the factory downpipes have been known to emit minor rattling noises when paired with the AWE Tuning S4 exhaust system. The possibility of rattling is eliminated with the addition of AWE Tuning downpipes. AWE Tuning downpipes are package discounted when purchased with the exhaust, or if they are purchased within one year of an exhaust purchase.
