AWE Tuning's 4.2 Exhaust Systems represent the most difficult, yet most rewarding, exhaust development projects in their company history. The 4.2 systems have paved the way for future exhaust technologies that can now be found in most every AWE Tuning Exhaust product. They have spent considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. Hand made in house one by one, these systems command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.
A recent install was quoted as saying, ""This is the best mod you could ever do to your cab. AWE Tuning's throaty intoxicating note with no drone makes the cab even hotter & wakes up the supercharger beast. I've had the exhaust in for a couple weeks now and can't imagine ever going back to stock. Once installed, you'll always want to paddle shift up/down to hear the supercharger boom between shifts...damn sexy.""
The magic behind this handcrafted exhaust is a combination of hundreds of R&D hours as well as the important ingredient of AWE Tuning downpipes, replacing the stock downpipes.
As with all AWE Tuning exhaust products, each TIG weld is hand finished internally, only butt-welded junctions are used, and flange openings are size matched to their ports, all to produce the smoothest flow possible. It is this intensive attention to detail that sets AWE Tuning exhaust products heads and shoulders above the rest.
AWE Tuning exhaust systems are hand built works of art, are award winning, and are what your S5 deserves.
About the downpipes

All tips are individually adjustable, so stagger and depth into bumper can be set according to personal taste.
And to answer the most commonly asked question: None of the components of our S5 Cabrio exhaust system affect or alter any of the emissions devices on the vehicle, and therefore are legal for street use.
