AC Fabrication is proud to announce its new lightweight aluminum cat-back exhaust for the F chassis M3/M4. Made to Burger Motorsports exacting standards the ACF exhaust system bolts to your factory or aftermarket downpipes for an easy swap with no cutting or modification of your factory system required. Heavy steel piping has been replaced with mandrel bent and tig-welded aluminum piping and the restrictive OEM mufflers have been replaced with custom sound tuned aluminum mufflers. Not only does this system offer a much deeper and richer sound than the factory exhaust but it also unlocks horsepower while shaving a whopping 40# of dead weight off the vehicle. The ACF exhaust is configured to accept your OEM or aftermarket exhaust tips. Exhaust tips are not included. Also note this system deletes the "exhaust flapper" valves found in the factory system. Features • 6061 grade aluminum construction for corrosion resistance and weight reduction • Stainless steel used in critical high temperature areas for a long life • Custom designed mufflers for a deep satisfying sound tone without excessive noise • Mandrel bent tubing featuring high quality TIG welds • Assembles using leak free VBAND flanges/clamps • Around 40lb lighter then the OEM exhaust system • Mounts to existing OEM brackets • Accepts OEM tips and any other tips made to fit the OEM exhaust • Made in the USA by ACF
