Fabspeed BMW M3/M4 (G80/G82) Supersport X-Pipe Valvetronic Exhaust System (2021+)

Get that aggressive and sharp BMW sound without any check engine lights or in cabin drone. The Supersport X-Pipe Valvetronic exhaust slip on system includes Fabspeed's high-performance Valvetronic axle back section and the "Double-X" maxflo mid-pipe for the perfect combination of sound, power, and weight reduction.SOUD:This system transforms the M3/M4 into a proper sounding sports car. You’ll actually hear a lot more turbo spool when letting off the throttle and you’ll feel the gritty iconic BMW straight six sound coming through the cabin under hard acceleration. Adding more pops and bangs on downshifts and giving a throaty rumble at idle.POWER:On our in-house DynoJet, this system made max gains of 25 ft/lbs of TQ at 3,300 RPM and 22 WHP at 5,500 RPM. That’s 26 crank HP! Take a look at our dyno graph and you can see that power is gained throughout the entire power band.
