BMW F80/F82/F87, M3/M4/M2 (S55) Big Single Mid Pipe

BMW F80/F82/F87 M3/M4/M2 (S55) Big Single Mid Pipe

Transform the sound, flow, and character of your BMW S55-powered M car with this Big Single Mid Pipe — engineered to reduce exhaust restrictions, enhance exhaust tone, and deliver a more aggressive motorsport-inspired driving experience.

Designed specifically for the twin-turbocharged 3.0L S55 engine, this Big Single Mid Pipe replaces the restrictive factory dual-pipe midsection with a larger single-pipe configuration, allowing exhaust gases to flow more efficiently through the system. The result is improved exhaust flow, reduced backpressure, enhanced turbo acoustics, and a significantly deeper exhaust note.

Manufactured from premium mandrel-bent stainless steel and precision TIG welded throughout, this system is built to withstand extreme temperatures and high-performance driving conditions while maintaining excellent fitment and durability.

Whether paired with factory downpipes, high-flow catted downpipes, or catless downpipes, this Big Single Mid Pipe delivers one of the most dramatic sound transformations available for the S55 platform.
