Dinan 20-25 BMW X3 M/X4 M (F97/F98) Free Flow Axleback Exhaust System - Black Tips

The "baby M's" of the 'X' family just got a bit more big brother like. With more volume and a deeper, more aggressive note courtesy of the Dinan axle back exhaust system, the F97/F98 now stand on the precipice of rivaling, or even surpassing, its V8 siblings --- at least, in regards to sound. With an intoxicating and menacing sound befitting of a high performance SUV the X3M/X4M holds its own amongst the pantheon of more traditional M's.
