Hey Guys, I was mowing over the pipe issue. Both my 05 and 08 still have the stock WR pipe and header. I saw that Pro Moto Billet makes an awesome Alum Anodized USFS tip with screen for the YZ pipes. I know that the YZ pipe and header is larger diameter than the stock WR pipe. Will the YZ pipe and header fit on the WR w/out any modifications? Also, where would I have Db issues? Kennedy Meadows, Big Bear, SBNF, SNF? any thoughts on this would be helpfull. Dube2 OUT!
