Bigger aftermarket exhausts can run tight against the M2's factory underbody brace. MMX's billet replacement fits in the original location but gives 15 mm more room for the pipes, without lowering the car's ground clearance. It also stiffens that part of the chassis.

What you get

  • 15 mm more exhaust clearance than the factory brace.
  • CNC-machined billet 6061-T6 aluminum, with excess material cut away to save weight.
  • Added chassis rigidity for steadier, more responsive handling.
  • Direct OE replacement that bolts into the factory position.
