For F12/F13 640i owners running the N20 engine: this is the AC Schnitzer dual sports exhaust - not a clone, not a generic 'sport' system, and definitely not OEM replacement. It’s the real thing, engineered for the chassis, not just bolted on.
Fits F12/F13 640i (N20 only) - no compatibility with N55 640i or 650i models; verify your engine code before ordering
Stage 1-ready fast road or track day use - decat option available separately, but this pipe itself is cat-back only
Stainless steel throughout, with polished twin 90mm tailpipes - built for daily driver durability and show car presence
Requires AC Schnitzer rear skirt (SE/Sport) or M Sport carbon diffuser - does not clear stock rear trim
