304 SS Performance Cat-Back Exhaust System with Dual Rear Exit by AWE Tuning®. Exhaust Type: Cat-Back. Exhaust Tubing Material: 304 SS. Main Tubing Diameter: 2.5″. Exhaust System Sound: Aggressive / Loud. AWE Tuning 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 crusing at part throttle, while also producing a war-cry wail when full throttle is applied. Sophisticated, refined, and powerful, all at once.AWE Tuning VW Mk5 GTI Performance Exhaust
