Love the tips, fitted the M5 diffuser just perfect. The best I have seen! Not sure if I liked the white spot on the diffuser though, would've kept it one-colored either white or black. Nice ride!
Wondering about the same on my car, but it will only be for the looks, not for the sound as it is a diesel engine.
If you're willing the share the price for this fitted (incl. the tips) I'd appreciate that, PM me if you don't want to share it in public.
