Overview
The B9 A4/A5's factory exhaust is tuned for refinement, leaving the 2.0 TFSI sounding flatter than it needs to. This valved catback system replaces the rear assembly with a more expressive setup — deeper tone and cleaner presence, with valve control to keep things civil when needed.
Why Upgrade?
- More expressive exhaust character than the factory system
- Valve control for sound adjustment — open for performance, closed for daily use
- Reduced back pressure through the rear exhaust section
- Stainless steel construction
- Direct OEM replacement installation
Built for the Drive, Not Just the Dyno
The B9's factory exhaust is tuned to disappear into the background — sensible for a daily Audi, but it leaves the 2.0 TFSI mostly unheard. Valve control means you keep both: quiet for the commute, more presence the moment you want it, with the change starting right where you'd expect on a catback.
