For S5 owners looking to fine tune the sound of their 4.2L even more, AWE offers Resonated Downpipes featuring resonators larger than the stock units, along with larger diameter tubing to produce a mellow sound volume. These downpipes are the perfect addition to the Touring Edition Exhaust for ultimate sophistication or to further tune the tone of the Track Edition.

The AWE No Check Engine Light Guarantee offers peace of mind against the appearance of Check Engine Lights when products are installed properly and used as intended, on vehicles with no additional modifications (with the exception of other AWE products intended to work with the product in question). No problems, no lights. Easy.
