There is actually a pretty good article in the Dec06 Dirt Rider magazine on pipes. They compare about 20 exhausts for noise, performance, and price. Although it is not CRF250X specific. The tests are done on a 250 and the requirement is under 96db (if I remember correctly).
Its a pretty informative article if your looking to upgrade your exhaust. I hope I helped
