AC Schnitzer Performance Quad Sports Exhaust Rear Silencer/Back Box for BMW X5M F85 & X6M F86 - Valved or Non-Valved, 90mm Quad Tailpipes, Matt Black or Chrome Tips, V2A Stainless Steel Muffler Upgrade

AC Schnitzer quad tailpipe rear section for BMW X5 M and X6 M, F8X platform

Transform the soundtrack and presence of your M SUV with this AC Schnitzer performance rear silencer and quad outlet setup. Built from premium V2A stainless for long term durability and a precision fit to the original mounting points, it delivers a richer tone, sharper throttle response and a stunning motorsport look.

Choose between the road-legal homologated version with factory-controlled valves or the track-use export option that runs without valves for a constant, assertive note. Tip finish options include classic polished chrome or stealthy matt black, both with muscular 90 mm outlets that fill the rear valance perfectly.
