The Fabspeed BMW M3 & M4 Intermediate X-Pipe offers a significant improvement plug and play” upgrade to the restrictive and quiet OEM double “H” pipe. Adding a significant increase in tone, volume, and power our double X-Pipe design uses two cast x-pipes
The Fabspeed Motorsport Intermediate X-Pipe exhaust relieves you of the subtle OEM sound and gives you the volume and tone that’s missing from the factory system. With a slight increase in volume on the throttle and a nice burble at idle. Downshift pops and bangs in sport mode are louder, but not obnoxiously so. This system has no drone at all cruising around town or on the highway.
