Rico...
I can promise you this, without the sugar coating.
If they are in fact big bore flange pipes, as they are listed, they will not work for you bike unless you either cut them off and have smaller flanges put on OR get reducers made.
I know you're gonna take 'em out of the box and try to match them up, there's gonna be enough slop in there to ring the flanges around like a cow bell for supper...I promise.
If I remember correctly, yours (and mine)...or stock banshee...exhaust flanges are 45mm OD. Those big bore pipes will probably be 48mm ID.
You're not making that up with an Oring....
Matter of fact, my pipes are off my bike now, I'll go measure the flange
Yep...45mm on my 10 mil cub...same as yours. I think my pipes are 46mm or so, and the Oring seals it.
