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!
