The AWE Track Edition cat-back exhaust for the Audi B9 S4 is a non-resonated system built to deliver a loud, aggressive tone. It uses straight-through downpipes and an integrated x-pipe as the lone filtering element, finishing with adjustable 102mm double-walled slash-cut tips with the AWE logo. Handcrafted from T304L stainless steel, it bolts on directly, carries AWE's fitment guarantees and a lifetime exhaust warranty. Note: this iteration is intentionally loud and final-sale for sound preference.
