Select the year of your Audi S4:
The best upgrade you can do to the turbocharged Audi S4/S5 B9 is a new exhaust system. The ideal option for those looking for versatility paired with impeccable performance is the VR stainless steel valvetronic exhaust system. With the VR Performance exhaust, your Audi will have noticeable heightened performance and a mind blowing new soundtrack to match. As a complete catback exhaust, it has been crafted from high quality stainless steel that is then TIG welded. As a direct bolt-on replacement for the OEM exhaust system. With our innovative valvetronic exhaust technology, your car can go from quiet to loud with the push of a button. Electronic valves are placed on the outlet of the muffler which control the sound. When closed, the exhaust flow goes through the single outter tip which is quieter. However when the valve is opened, the exhaust goes straight out giving you an exciting sound to your turbocharged Audi.
The exhaust system includes all the nessecary electronic parts to equip the car for its valvetronic function. As a complete dual exhaust system, the 70mm polished piping gives you plenty of exhaust flow over stock. Adding style to the rear end is a set of these quad 90mm VR Performance exclusive design carbon fiber tips. Each tip features a cast inner portion that is wrapped in carbon fiber with vented slits, then adorn with the VR Logo. This is a direct-fit replacement exhaust that works with OEM or race downpipes.
