Overview
The factory exhaust on the B8 and B8.5 S4/S5 is quiet by design. This valved catback system replaces it with a more expressive setup, giving a deeper, more defined tone that can be adjusted via the valve control.
- Deeper, more characterful exhaust note than the factory system
- Valve control allows sound level adjustment for different situations
- Reduced back pressure through the rear exhaust section
- Stainless Steel construction for longevity
Driving Experience
The B8's factory exhaust is tuned to disappear into the background — sensible for a daily Audi, but it leaves the 4.2L V8 mostly unheard. Valve control means you keep both: quiet for the commute, the V8's real character the moment you want it.
