MAD BMW M340 M440 Axleback Exhaust (G20 & G22)

MAD BMW M340 M440 Axleback Exhaust (G20 & G22)The 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.
