I test drove an Z4MC this past weekend. The mufflers had been taken off. The sound was VERY nice, and I didn't feel any loss in performance, as a matter of fact it felt very strong (had 101,000 miles on it). Just wondering, is that just a simple modification where you take out the mufflers and weld pipes straight through? Does it have any effect on emissions? Once again, I really liked the sound!

I tried searching but couldn't find exactly what I was looking for, and I apologize for my ignorance on the subject.
