I got the FMF factory 4 exhaust on my 05 wr450. Its going to pop a little. Don't let it bother you. You might be a little lean.

I run 48/168 jetting. I have the jd jetting kit with the red needle in the 3rd position. My bike runs good anywhere from 2500-8500 feet. I could probably dial it in better, but its been this way for a couple of years with no problems.
