BMW F90 M5 Fully Valved Cat-Back Exhaust System (Pre-Order)

Transform your F90 M5 with our Fully Valved Cat-Back Exhaust System, built to free up the legendary S63 twin-turbo V8. Experience a dramatically deeper, more resonant note that unleashes the engine’s true character — a direct bolt-on with no need to cut into your factory exhaust.

Deeper, More Aggressive Sound: Say goodbye to the muted factory tone and hello to a thunderous V8 growl that turns heads everywhere you go.

Optimized High-Flow Design: Engineered for maximum airflow and a fuller, more aggressive exhaust note across the entire rev range.

Easy Installation: Designed for hassle-free bolt-on installation (professional installation recommended).

Valve Controller: Valves can be routed to be opened or closed with your factory M Buttons, or use our controller to open them all the way. NOTE: The factory buttons do not fully open your valves when revving in Park or driving at lower rpms. If you want to fully open your exhaust, our remote will open your valves completely and allow for maximum sound whenever you want it.
