AWE Non-Resonated downpipes for the B8 4.2L S5 use larger-diameter, straight-through tubing to create a more aggressive, uncorked exhaust tone. These downpipes are intended as a complement to AWE Touring or Track Edition systems to increase volume and character, and are designed for direct fitment to existing exhaust layouts while preserving compatibility and AWE's fitment guarantees.
