BMW M550i xDrive Performance Exhaust by Dinan — Axleback, Free Flow, Black (2018–2023). A precision-built axle-back that brings a deeper V8 tone and measured gains to the G30 M550i.

Dinan’s free-flow layout reduces back pressure for sharper response, while the factory computer-controlled valves keep it composed in normal driving and open fully under load. Drone abatement preserves cabin comfort. Constructed from 100% 304 stainless steel and finished with four 4 in. clamp-on, double-walled ceramic black tips with laser engraving. Straightforward bolt-on installation with included hardware. Dyno results: +8 hp and +6 lb-ft at 6600 rpm.
