thanks guys. The pipes are PT Mids. Had some fmf's on there and they were nice but the PT's made the power much more user friendly in the woods. Also has 2 into 1 carb- 35mm. +2+1 arms, works shocks and a 4 degree key. It runs great. There is a very small hesitation off the bottom but hopefully my order from jetsrus will cure that problem in the near future. Should be ordering a -2" swinger from JL in another month or so and will bump the compression a bit to help out with bottom end response. Long term plans are to install a 4mil crank with HJR trail porting. I've owned a number of quads (a few 450's) and I have to say that this bike is my favorite even for woods. Sure it's not as easy as a thumper in the tight sections but I think that's half the fun. Love me the smell of that 2 stroke motor in the morning
