The S5 Track Edition Exhaust is known for its powerful, raw V8 rumble. Still for the daily driver, this "noticeable" system lets them know you're coming. And for S5 owners seeking an even more aggressive sound, we offer our Non-Resonated Downpipes. Our Non-Resonated Downpipes eliminate an additional set of resonators from the car, to produce a louder and deeper tone to the exhaust note. All versions of our S5 4.2L Exhaust System come with 90mm (3.5 inch) slash-cut Tips, available in standard Chrome Silver or AWE's Diamond Black finishes. The tips sport engraved AWE logos and are double-walled to ensure a mirror polish, even under hard usage. Each tip is individually adjustable, so stagger and depth into bumper can be set according to personal taste. Please note that this is a loud system and buyers should be aware. This product cannot be returned or exchanged based upon sound satisfaction.
