Take a listen to our new B8 S4 valved exhaust system!

The full exhaust system is made from high quality brushed T304 stainless steel with TIG welded joints for an exceptional look and durability. Exhaust gases are channeled through the integrated x-pipe, your choice of a resonator or a resonator delete section, and then to the 3 chamber in house designed mufflers where you, the driver, are in control of where the exhaust gases go from here. With the valves open, we showed gains of 19 WHP and 16 WTQ on our B8 S4 equipped with a Kohlefaser Luft-Technik intake and a stage 2 tune with pulley!

In normal, comfortable driving conditions, the valve remains closed and exhaust gases are directed through the channels of the mufflers, where sound reduction takes place. To quench your passion for shear driving pleasure, simply pressing the "valve open" button on the remote key fob unleashes a straight-through, raw, unedited exhaust symphony. When the pneumatically actuated exhaust valves open, exhaust gases are channeled directly through the valved sections of the mufflers for an unrestricted, passageway.
