Primary Sport Cat Downpipes
Primary sport cat downpipes for the BMW F10 M5, 2011+, replacing the factory catalytic converters with German manufacturer of the high-flow catalytic converters Fabspeed fits in its sport cat products. 200-cell German catalytic converters for a more aggressive exhaust sound and better throttle response, while keeping emissions compliance — Fabspeed guarantees no catalyst-related check engine light. Built from T304L stainless steel with CNC-machined flanges and laser-cut brackets, made in-house and dyno-developed at Fabspeed. The two downpipes (marked left and right) fit seamlessly with the factory rear cat-back system or any aftermarket exhaust designed to accept the factory catalytic converters, and include installation hardware.
