aFe MACH Force-XP Cat-Back Exhaust – BMW M3/M4 (G80/G82) S58

OVERVIEW

The aFe MACH Force-XP Cat-Back Exhaust unleashes the full character of the S58-powered M3 and M4 with a free-flowing, aggressive note and reduced weight — while retaining the factory-style valves for street-friendly manners. Constructed from mandrel-bent 304 stainless steel stepping from 3″ down to 2-1/2″, it outflows the restrictive OE system and finishes with a set of aggressive quad 4″ tips. A direct bolt-on using factory mounting locations.
