It would look good wouldn't it!
I can either go with OTRs racing headers. A twin exhaust system

Or go with the only 2 into 1 low exhaust I can find. Its by GPR

only thing is, its for a 2004 xt660... the engine looks the same though.
Anyone know if the engine is the same?

I can see the 2 into 1 being lighter, other than that anyone have any idea what it will mean for the power???

Im thinking of chopping the rear sub frame off, as its too high. I hate the seat sloping forwards. makes the hips rotate forward n u end up sitting on ya nuts! ... so Ill make a lower angled subframe on it, allowing for a flatter seat. An also make it so it can take a rear safari tank... then build a bit of an exo cage/panier racks around it... or just sling one of them giant loops over it.
