Buying the M sport finishers...
If you are like me and didn't want to spend the extra money...Don't be like me just buy them. It won't be what you expected unless your exhaust person is a god.
These finishers are the same tips you already have (Msport) guys. You also get two tips. If your cool like me have
r33_RGSport put your order in and pay him to black them out on your white and black themed X5's because we aren't original and it looks dope yo. But like said before the M Performance finishers include the Flap mechanism but no flap inside and no spring so the system does not flip out.
