A true dual 3” T304L stainless steel configuration featuring a bespoke, straight-through center resonator specific for the 2.9TT, topped off with AWE’s proprietary drone-canceling solution, 180 Technology®, in the rear. The result is a menacing, aggressive soundtrack throughout the range with a drone-free cabin experience under cruising conditions. This exhaust resides at the intersection of exotic aggression and highway comfort for the S6/S7. Quad 4.5" double-walled, slash-cut tips in your choice of chrome silver or diamond black. AWE No CEL Guarantee, Perfect Fitment Guarantee, and Lifetime Warranty come standard.
