Our exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. We 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. Our exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once. Our 3.0T Exhaust System represents the most difficult, yet most rewarding, exhaust development project in our company history. Sophisticated, refined, and powerful, all at once. The S5 Exhaust is the perfect performance compliment for the daily driven S5. Highlights of the 3.0T S5 system Hand-crafted, every detail of these exhausts was labored over to ensure maximum performance and longevity: + 8hp, +9tq at the crank Increased pipe diameter to 2.5?? to better let the engine exhale Strategic elimination of mufflers to release tone when uncorked Available with Polished Silver or Diamond Black adjustable tips Engineered, developed, tested and manufactured in-house Thick .065" wall T304 stainless steel tubing Stainless steel TIG welds High quality stainless steel band clamps Stainless steel center muffler with OEM grade stainless steel wool and German composite packing material Optional Downpipes for fine tuning sound volume Lifetime Warranty For S5 owners looking to fine tune the sound even more, 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. 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. Our exhaust systems are hand built works of art, are award winning, and are what your Audi deserves.
