Description
Looking at the Audi B8 S4/S5, you'd expect a decently aggressive exhaust note to match the aggressive styling, but unfortunately, Audi did not deliver on that. Simply put, the B8 S4 and S5 both have quiet and tame exhaust notes, but luckily VR Performance fixed this issue with their stainless steel Valvetronic exhaust system.
This exhaust system features dual 2.5-inch (63.5mm) mandrel-bent tubing, which flows much better than the stock exhaust system. With more exhaust flows comes more power and more efficiency. Not only that, but this exhaust system is also lightweight at just 66.15lbs for the entire system.
The integrated Valvetronic system allows the exhaust flow to be routed through or around the mufflers, allowing you to change the exhaust note on the fly. Opening the valves will give off an incredible tone that is unmatched, while you also have the option to close the valves for an elevated factory-sounding exhaust.
Features:
High-quality 304 stainless steel tubing
Open valves bypass muffler for an aggressive tone
Closed valves will give an elevated factory sounding exhaust
Dual 2.5-inch (63.5mm) mandrel-bent tubing
Lightweight 66.15lb construction
Significantly reduces back pressure
Precision fitment thanks to 3D scanning and CAD Modeling
No modification is required for installation
