Hey guys, my 03 wr is Canadian and does not have any way of changing or removing the baffle in the pipe as it has the tip welded in. Would i benefit from a stock yz 450 pipe and if so, do i have to rejet the bike for it? thanks

You will probably benefit from the yz pipe, you will also probably have to up the main. Get the pipe, do a plug check and jet from there. Black plug= too rich, white plug= too lean, tan plug= perfection. (Although I like to run my bikes on the darker side of tan so I'm not lean if I ride in lower elevations or temperatures.)

Maybe you could consider looking at this very cheap modification I did, if you have the same pipe as the Aussie version.

To answer your question, yes I had to rejet to achieve the best performance from the bike.
