Same here. Not much difference. My muffler shop can take the muffler apart and replace the perforated pipes with solid ones for $500. That would be better.
I still admit that the exhaust on the X5M sounds so much better than the new M3/M4 stock. I love how loud the crack is between WOT gear shifts.
