I need some help on the selection of pipes for heavy trail riding and the occasion mud play. I planto run a 420 with nitrous and haven't picked out the carb(s) yet either so things are still pretty flexible. The nitrous thing just was inspired the other night when I say (2) 250R's and YFZ450 strolling past my house. This phenomena has continued for the past week. They will get theirs soon. I just need to blast the shit out of them. I sure that nice new billet mounted taillight will look real nice 200 ft ahead of a YFZ450 and some 250R's.
