AWE Tuning's B8.5 S4 Exhaust system represents the most difficult, yet most rewarding, exhaust development project in their company history.  AWE Tuning spent considerable time and effort during development to achieve a nice settle tone when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied.  AWE Tuning spent over 170 hours massaging the sound quality and developing special Helmholtz noise cancellation resonators tuned to eliminate any and all drone in the 1000-2200 rpm range.

AWE B8.5 S4 exhaust system is capped off with attractive 90mm slash cut tips featuring the AWE Tuning logo. These tips are double walled to ensure a mirror finish even under hard usage. Choose between the classic Polished Silver slash cut tips, and luscious Diamond Black slash cut tips, or distinctive Diamond Black oval shaped tips to help your car stand out from the pack. Each tip is individually adjustable, so stagger and depth into bumper can be set according to personal taste.
