Dinan Freeflow Stainless Exhaust with Polished Tips for BMW G30 M550i
Upgrade your BMW G30 M550i with the Dinan Freeflow Stainless Exhaust and unlock the refined performance sound this V8 deserves. This premium rear exhaust system reduces back pressure to improve exhaust flow, delivers a deeper, sportier tone under load and keeps things civilised at cruising speeds. It retains the factory computer-controlled exhaust valves for true valved behaviour, so you get quiet when you want it and a pleasantly aggressive note when you put your foot down. No intrusive low-RPM drone in the cabin, just a rich, authentic BMW M550i sound outside.
