AWE Tuning Touring Edition Exhaust System Audi S4 (B8.5) 3.0T

Product Description

The AWE Tuning 3.0T exhaust system represents the most comprehensive exhaust development project in their company history. The 3.0T systems have paved the way for future exhaust technologies that can now be found in most every AWE Tuning exhaust product. We have spent considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. Handcrafted in-house, these systems command respect while remaining sophisticated, refined, and powerful, all at once.

Sound Perfection: AWE Tuning 180 Technology®
As exhaust gases exit the 3.0T engine and flow into an AWE Tuning 180 Technology® equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves re-join the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies.

Tip options


Tip options are as follows - all of which include the AWE Tuning logo, and double walling to ensure a mirror finish even under hard usage.
90mm slash-cut diamond black tips
90mm slash-cut chrome sIlver tips
102mm slash-cut diamond black tips
102mm slash-cut chrome silver tips

All tips are individually adjustable, so stagger and depth into bumper can be set according to personal taste.

Please note: 102mm tips will only fit on 2013+ S4s. To accommodate the 102mm tips, the muffler itself had to be re-engineered, and as such, tips cannot be changed from 90mm to 102mm without the purchase of a new rear section of the system. Questions on this? We’re here.

About the downpipes

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 volume. Our 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.

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.

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.

Looking for a lower cost option? Look no further than the AWE Tuning ® Track Edition Exhaust.

For those open to a louder part-throttle experience, we're introducing the AWE Tuning ® Track Edition Exhaust. Same power and craftsmanship, with less mufflers and price. More, right here.

Read this, too

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.
