Does anyone have any info on modifing the stock pipe/baffle? I thought I read somewhere that you can buy a race endcap from Honda OR drill the end out... It looks like the baffle is tack welded in... I just bought an 04 XR650L and will soon be ripping the smog stuff off, and jetting. I don't want to spend the bread for a high dollar pipe... any suggestions? OR should I just run the stock baffled pipe as it is? thanks!
