I have Leos installed on my '05 950. They are loud without the baffles, but not unacceptably so (and only when you get on the throttle). Construction and aesthetics are good, especially given the price. I did find them to be a PITA to install, though. The fit between the midpipe and the subframe tabs is extremely tight, and the right can hangs lower than the left (not just on my bike...many people have this problem). The cans also just barely clear the Givi rack I have on my bike...only by a few mm on the right side. Still, I have about 10,000 miles on them, and they have been great. I did rejet...my gas milage is in the low 30s now, but the throttle response is outstanding.
