AWE Tuning Audi B8 / B8.5 S4 3.0T Touring Edition Exhaust - Chrome Silver Tips (90mm)

The AWE Tuning 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. AWE Tuning has 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. These systems are handmade in-house and command respect while remaining sophisticated, refined, and powerful, all at once.

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, the exhaust system also controls 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.

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 keeps AWE Tuning exhaust products heads and shoulders above the rest.
