Fabspeed BMW M3/M4 (G80/G82) Intermediate X-Pipe (2021+)

The factory M3 and M4 use a double H-pipe in the middle of the exhaust, and it keeps the S58 quiet and a little muted. Fabspeed's intermediate pipe swaps that section for a design built around two cast X-pipes. The result is a fuller, louder exhaust note without turning the car into a drone box on the highway.

What you get

• Two cast X-pipes in place of the factory double H-pipe section.
• More volume and a deeper tone, with a modest step up in sound when you get on the throttle.
• A light burble at idle, plus louder overrun pops in sport mode that stay on the tame side.
• No drone while cruising, in town or at highway speed, per Fabspeed.
• Plug-and-play fit that bolts in where the factory pipe was.
