Axleback exhaust systems generally include what's behind your rear axle. These are among the easiest of exhaust upgrades to install, and give you an instant upgrade in sound.
Supersprint Race mufflers for the F8X M3/M4 combine Italian craftsmanship with 60 years of exhaust tuning experience to deliver a muffler upgrade with an intoxicating exhaust note. The Supersprint Racing mufflers build on the M3/M4's muscular exhaust with extra punch and volume. This system does not use the muffler diverter valves of the stock system so it's like getting the Sport Plus sound with an Italian twist. This is the muffler section only (left and right mufflers) and will be a slip-fit to original factory resonator. Choose from 80mm or 90mm tipes in chrome, satin silver, or black.
