AWE Tuning 3.0T Touring Edition Exhaust (90mm) for B8/B8.5 S4
Our 3.0T exhaust system represents the most comprehensive exhaust development project in our 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. Hand made 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.

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.
