For the G22 Coupe and G23 Gran Coupe owner who’s already swapped the bumper, ditched the catalytic converter, or just wants their fast road 4 Series to look like it means business - this is the diffuser that slots in without drama.
Exact fit for G22 and G23 chassis - no N55, B58, or M440i vs M4 debate required; it fits both
Gloss black ABS - not carbon fibre, not matte, not ‘carbon-look’ - just deep, durable, OEM-matched gloss
Round-tip ready - cutouts sized for standard 90mm round exhaust tips; works with decat pipes, stage 2 setups, or stock backboxes
