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

Fabspeed's Supersport X-Pipe system pairs its valved axle-back with the "Double-X" maxflo mid-pipe. It gives the M3 and M4 a sharper, louder straight-six sound with more audible turbo spool, without a check engine light or cabin drone, and it saves weight over stock.

What you get

• Valved axle-back plus Double-X mid-pipe as one slip-on system.
• More sound throughout: turbo noise off throttle, a gritty six-cylinder note under load, a throaty idle and more pops on downshifts.
• Measured gains. On Fabspeed's own dyno peak gains were 22 whp at 5,500 rpm and 25 lb-ft of torque at 3,300 rpm.
• Three tip finishes: satin black, carbon fiber or polished.

Good to know

• Fabspeed states no check engine lights or in-cabin drone with this system.
