BMW G90 / G99 M5 X-Pipe Exhaust System
Designed and fabricated specifically for the all-new BMW G90 & G99 M5 platform, this X-pipe system transforms the factory exhaust note into something worthy of the twin-turbo V8.
The OEM exhaust is quiet, restrictive, and heavily filtered. Our custom-designed X-pipe unlocks a deeper more exotic tone while improving overall exhaust flow.
Hand-fabricated with precision TIG-welded merge sections, this system delivers a clean OEM+ fitment with motorsport quality.
