Great mods and congrats - I am not one to do a lot to my cars but this time I really think the M5 needs an exhaust or some type of "cabin based" noise solution. I really really hate how quite it is at below 4k rpm levels - almost feels like a 7 series. The other item that is starting to bother me is the seat bolsters - I didn't think I would miss them but I think my new diet is shrinking my love handles and I am starting to slide around bit more
Need to work on the lats or something..
