Your RS4 is a highly engineered performance machine and deserves an exhaust system designed with the same attention to detail. Sophisticated CAD modeling software allowed us to create a system that performs and sounds worthy of this autobahn stormer.
Our exhausts have earned praise from owners and the press alike, due to their unique "Jekyll and Hyde" personality. We spend 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. Our exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.
If you love the sound of an muscular V8, but need something more manageable for transporting clients, go with our Resonated exhaust system, either with or without our high flow downpipes.
If you want to bask in the sound of your V8 and enjoy a loud exhaust note, choose our Non-Resonated exhaust system. Our Non-Resonated system with our downpipes is as aggressive as it gets!
Here are some of the highlights of our RS4 Exhaust system. Each feature was chosen for performance and longevity reasons, and when making your exhaust decision you should settle for nothing less:
- +11 Horsepower and 11 FT LBS of Torque at the crank with the entire system
- +7 Horsepower and 5 FT LBS of Torque at the crank with catback only
- X-Pipe design for maximum exhaust scavenging and better balance between cylinder banks
- Will mate up to factory downpipes without modification
- Fully mandrel bent tubing 2.5" in diameter
- Thick .065" wall T304 stainless steel tubing
- Stainless steel TIG welds
- High quality stainless steel band clamps
- Developed in-house on our AWD Mustang Dyno
- Catback saves 14 lbs compared to stock
- Downpipes save 7 lbs compared to stock
- Lifetime Warranty
The cat back system is topped off with our gorgeous 3.15" (80mm) slash cut exhaust tips. The tips sport engraved AWE Tuning logos and are double walled to ensure a mirror polish even under hard usage. They are available in with your choice of Polished Silver or Diamond Black finishes.
For the RS4 owner looking for the pinnacle of performance and sound we offer our high-flow downpipes. The OE downpipes have a restrictive cat located right after a bend in the tubing, causing exhaust gas flow turbulence in the system. By placing a high-flow HJS catalytic converter further downstream, we've smoothed flow and allowed air to move more freely. Our downpipes will mate to our cat back system or any system designed to work with the stock downpipes. Also, our downpipes eliminate a set of resonators to produce a deeper, more powerful engine note.
As with all AWE Tuning exhaust products, each TIG weld is hand finished internally 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.
Our exhaust systems are handbuilt works of art, are award winning, and are what your Audi deserves.
Please note that due to the use of high flow catalytic converters, our downpipe section is legal only for racing vehicles which may never be used upon a highway.
