For F06 640d owners who’ve already ditched the diesel particulate filter and want proper theatre - not just volume - this AC Schnitzer quad exhaust delivers four 90mm chrome tips, twin-pipe routing per side, and that unmistakable low-bass growl on lift-off.
Fits F06 640d chassis only - confirmed for M Sport models with AC Schnitzer carbon diffuser, or SE/Sport with AC Schnitzer rear skirt; no fitment on standard rear aprons
Not a decat or downpipe - this is the rear section only; retains OEM catalytic converters and resonator mounting points
