Sound check

Has anyone had a sound test done on a YZ450 exhaust with a PMB endcap and silent insert? I'm curious because I want to take my bike to the woods this summer and want to be sure I'm legal. They haven't gotten too excited about sound checks out in the local desert here. In fact I haven't heard of anyone being tested yet.

Yeah I had all the rangers at StonyFord checking my stock pipe with the PMB insert and it passed on the sound meter.
