Description
The Audi B9 S4 needs a more aggressive tone, which you can easily achieve with the VR Performance titanium catback exhaust! The Valvetronic feature allows for the exhaust to be tame and factory sounding with the valves closed. With the valves open, the exhaust bypasses the muffler resulting in less restriction and a much louder exhaust note
The VR Performance titanium exhaust only weighs 38.72 lbs which is nearly HALF the weight of your factory system. The 3-inch (76mm) diameter tubing throughout the exhaust significantly reduces backpressure. The muffler outlets are 2.5-inch (63.5mm) to allow for a slightly better tone than stock without being too loud.
