yz/wr rear pipe

does any one know if my wr 400 would run better with a YZ pipe on it. I dont have much $$$, but there are alot of guys around here selling there stock Z pipes because they have spent the $$$$ for an after market.

thank'z Zoo

In a simple answer Yes. The YZ can is a straight through flow design with no spark arrestor. To mount it on a WR you will need the YZ rubber insulator and longer bolt for the upper mount.
