About the downpipes
Resonated Downpipes (strongly recommended for S-tronic cars) feature resonators larger than the stock units in order to produce a mellow sound volume.
Both our Resonated and Non-Resonated Downpipes feature larger than stock tubing diameter.
Downpipe + exhaust packages offer the most cost-effective solution.
- 1 driver side 6ex section (CG1)
- 1 passenger side 6ex section (CG2)
- 2 resonator (or tube) section (CG3, 5)
- 6 M8 x 30mm SS bolt
- 6 M8 washer
- 6 M8 copper exhaust nut
- 2 manifold to downpipe gasket
- 2 2.50” exhaust band clamp
Downpipe installation tip
Installing downpipes on these cars is arduous given the placement of the factory bolts. AWE had so much trouble that they made an AWE Tuning-grade tool to make it easier. If you're planning an install, our Downpipe Removal Tool is a must have.
Upgrading to downpipes later
Not sure if you want to do the full package yet? No worries. If you purchase a Downpipe-Back system alone, you have one full year from the date of Downpipe-Back system purchase to buy the complementing downpipes, for the price difference between the Downpipe-Back system alone and the package price (price at the time of downpipe purchase). This is for original owners only, and is valid through AWE Tuning directly or through any authorized AWE Tuning dealer, so long as proof of the original Downpipe-Back purchase can be provided
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.
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.
