AWE Cat-Back Touring

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. AWE 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. Handcrafted, every detail drives toward maximum performance, quality and perfect sound. Notes: In limited cases, the factory downpipes have been known to emit minor rattling noises when paired with the AWE S4 exhaust system. The possibility of rattling is eliminated with the addition of AWE downpipes. AWE Touring Edition Exhaust for Audi B8 S4 3.0T - 3.5" Diamond Tips.
