Our exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. We spend 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. Manual transmission system is a catback design, Tiptronic is a midpipe back design and reuses the stock downpipe. Each system is mandrel bent T304 stainless steel, and the manual transmission model is a full catalytic converter back design. Since the catalytic converter resides in the engine bay with the A4 2.0T, an exhaust system is only considered a catalytic converter back design if the downpipe that comes off the catalytic converter is also part of the system. Not only does our manual transmission system include a downpipe, but it is a whopping 2.5" in diameter, guaranteeing maximum flow even with big turbo kits. The AWE Tuning exhaust makes the stock system look puny in every way. Our straight through resonators and mufflers ensure flow while keeping the noise level down to civilized volume, even a touch quieter than our B6 A4 system. There is very minimal drone with this system. Our signature 3.5" Straight Cut beveled exhaust tips etched with AWE Tuning logos are double walled to ensure a mirror polish even under hard usage. Available in your choice of Polished Silver or Diamond Black finish. Both tips are individually adjustable to provide for perfect fitment even with S-Line, European, and aftermarket bumpers. Also available: B7 A4 2.0T Quad Tip Exhausts! This beautiful Quad Tip Exhaust has all of the features that made our Single Tip System such a success: Perfect Fitment, High Quality Construction and a Terrific Sound. Our signature beveled exhaust tips, 3.15" Slash Cut for the Quad Tip, sport laser etched AWE Tuning logos and are double walled to ensure a mirror polish even under hard usage. As with our Single Tip systems, tips are individually adjustable. This unique Quad Tip Section will set your car apart from the rest. Available with both Polished Silver Tips and as a Limited Edition with Diamond Black Tips. The total number of systems sold with Diamond Black Tips will be limited, so order yours while it's available! In order to install our Quad Tip Exhaust, it is required that you equip your car with a B7 S4 Rear Valance. They are readily available at your local dealer. Once obtained, the rear valance needs to be painted before installation. The OEM Part Number for the B7 S4 Rear Valance is: 8E0807521M1RR.
