Welcome to the mothership of 3.0T exhausts.

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 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.

Track Edition:

The lower priced sibling of our renowned Touring Edition Exhaust, the Track Edition is made of the same quality 304 stainless, is crafted in house, and delivers the same power gains. The difference comes in the removal of AWE's sound-cancelling 180 Technology™ rear-mufflers, which can be found on our Touring Edition Exhaust.

This system will produce a louder tone in the mid range.

Important Notes!

• Given the removal of the rear-resonators, this system cannot be returned due to sound.
• S-Tronic owners beware: This system will be especially loud at part throttle.

As with all AWE exhaust products, each 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 exhaust products heads and shoulders above the rest.
