Yep, I got mine on and installed today thanks to the help of this write up!
When I was pushing the new exhaust into the header it was very very tight and hard to get it lined up with the mounting bracket, was it that hard for all of you?
After removing the big box the bike trimmed down alot of weight. Then I slipped the m4 into the pipe that goes straight into the header pipe. I aligned the m4 and carefully pushed and twisted it in not catching the soft stuff inside the pipe and the m4 went in good. I twisted the m4 up and the bracket somewhat made it but, I did mount and screw everything in good. The end of the m4 does end just past the foot peg.
