I did the full Remus exhaust. Removed the header and the can.
Never found adequate feedback on this- so here's my 2 cents...
Cost me $1200.
Had to grind down one of my radiator crash bar connections where they bolted together- just took a little off, don't think it will affect their integrity.
Have to put 1/2" extensions on the bolts for the skid plate.
It took care of the power lag off the line. I can wheelie it now with little effort- so it's an obvious increase in power. I haven't taken it for a long ride yet- so haven't seen how it throws off heat- but the old pipe really bothered me with how hot it got.
The bike definitely has a deeper tone now, but not too annoying...
Depending on what you want from your bike- this mod is not for everyone... I'm happy with it though.
I've also up-graded fork springs (a mandatory mod in my book if you are off-roading).
