anyone install a remus exhaust?

i own an SLK i hope it helps tho, i installed a Remus exhuast, i had the non sport package bumpers and i need to cut the rear bumper, if i had gotten the sports package, than i would not have had to; also depends if your gettin dual or single tipped exhuast, if ur gettin single u will defintly not have to cut the bumper, if u get twin, u might, but chances are u won't have to, also you have to know how many millimeters each tip is, i have a dual tip with each being 90 mm circles (2 x 90mm)
