Sku # : awe-tuning-s4-b6-exhaust-ng
Exhaust Option
Downpipes? Yes/No
Developed in-house on AWE Tuning's AWD dynamometer, with a critical ear lent to sound volume and tone character. Featuring AWE's distinctive double walled taper tips in a 3.5" (90mm) diameter, this system looks fantastic on the car.

AWE's exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. AWE spends 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. AWE's 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.
Silver Finish

Black Diamond Finish


AWE B6 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.

Each tip is individually adjustable, so stagger and depth into bumper can be set according to personal taste.
