I had my F Sport exhaust installed last year. That price posted above was a steal. Paid $1250 for mine from my local dealer. Took down my bumper and drove down the street to a local muffler shop. $50 to install. Couldn’t get the damn stock exhaust tips off. F Sport diffuser wouldn’t have fit with those on. Muffler guy asked, where’s your bumper at? Lol!
I did install the lip spoiler myself. I went with drilling the holes. The stencil does not line up correctly. Had to mess with it.
