New rear diffuser help!!
I want to upgrade the rear diffuser to a carbon fiber one or something more aggressive in carbon or gloss black.
My questions are if I can just remove the black trim piece on my current bumper and install an after market one, or do i need to buy a whole E63 rear bumper for it to fit?
Also do they make any ones that will fit my current dual exhaust setup? Would save alot if i don’t have to switch to a quad setup instead.
Thanks for the help
