Imola trust me you will love it. it will be deeper but still drivable every day. now I have "supersport" exhaust and it is louder and deeper but with time is really annoying me and I am thinking of going back to stock exhaust and x pipe. especially when I drive long routes.
PS all others worried about fuel economy on V8 engine powered SUV...you are in wroooooong movie...sell your bimmer and get your self some girly prius or vw. No hard feelings...it is for your own good
