Product Details


AWE's 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.

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.
