BMW F90 M5 Titanium Valved Cat-Back Exhaust – S63 Sound Reimagined
The F90 M5 is a twin-turbo weapon trapped behind one of the quietest factory exhausts BMW has ever built. This titanium valved cat-back wakes it up instantly. More presence. More tone. More personality. The way an S63 should’ve sounded the day it rolled off the line.
Crafted entirely from Grade 5 titanium with true 3.0" tubing and a forward large cross-section X-pipe, this system transforms both performance and sound. Daily-friendly when closed. Ferocious when open. No drone, no buzz, no fake theatrics—just clean, exotic V8 noise.
Why This Hits Harder
Forward Large Cross-Section X-Pipe:
- Improves scavenging and deepens exhaust tone
- Eliminates harsh rasp common in most aftermarket systems
- Especially effective on downpipe-equipped setups
3.0" Titanium Free-Flow Design:
- Reduces back pressure for faster response and stronger top-end power
- Delivers major weight savings over stainless steel systems
- Produces a cleaner, more refined exotic V8 sound profile
True Valved Control:
- Integrates with OEM drive modes (Sport / Sport+) or standalone remote
- Instant control over exhaust volume anytime
- Full flexibility for street, highway, or spirited driving
