aFe MACH Force-XP Cat-Back Exhaust – BMW Z4 M40i (G29) B58

OVERVIEW

The aFe MACH Force-XP Cat-Back Exhaust transforms the B58-powered Z4 M40i with a deeper, more aggressive tone and freer flow, without sacrificing daily drivability. Built from mandrel-bent 304 stainless steel that steps from 3″ down to 2-1/2″, it outflows the restrictive factory system while retaining the factory-style exhaust valves for a civil cruise and an open, race-inspired wail on demand. A direct bolt-on that exits through aggressive quad 3-1/2″ tips.
