Description
Enhance your BMW M3/M4 (G80/G82) with the Fabspeed Supersport X-Pipe Valvetronic Exhaust System, designed to deliver a more aggressive, sharper exhaust note and boost performance without any cabin drone or check engine lights.

Whether you are hitting the track or enjoying daily driving, this system guarantees a true sports car experience.
Superior Sound Quality:
This exhaust system completely transforms the auditory presence of your BMW M3/M4. Under heavy acceleration, you’ll feel the gritty, iconic BMW straight-six sound reverberating through the cabin. Turbo spool becomes more noticeable when letting off the throttle, while the system adds satisfying pops and bangs during downshifts. At idle, you’ll notice a deep, throaty rumble, providing your M3 or M4 with the sound presence it deserves.

Tested on Fabspeed’s in-house DynoJet, this system offers impressive power gains throughout the RPM range. Expect a maximum increase of 25 ft/lbs of torque at 3,300 RPM and 22 WHP (wheel horsepower) at 5,500 RPM, equivalent to 26 crank horsepower. These gains, along with improved throttle response, ensure a thrilling driving experience and noticeably enhanced performance.
