MAD BMW M340 M440 Axleback Exhaust (G20 & G22) x3 m carbon fiber splitter • Increased Turbo SoundThe MAD BMW M340 M440 Axle Back Exhaust System is designed to deliver a bold sound upgrade without unnecessary parts or added cost. On this platform, a full catback is simply not needed. The factory midpipe is already a single design and is completely non restrictive, with no cats and no resonators. Replacing it with another single midpipe offers no real performance or sound benefit, so this system focuses where it actually matters: the axle back.
