OK, Took the insert out of the GYTR exhaust on my 02 WR. I wrapped the spark arrestor with one layer of packing. I warmed the bike up today and tested the noise level. Just as I thought, it is not yet legal. It was around 102 dB at 1/2 throttle. I held the meter 45 degrees off the end of the pipe, 20 inches away (thats how they sound check here in Michigan at our club rides.) The bike idles @ 92 dB! At 1/3 throttle, it was around 99 dB. I am going to try to wrap some more packing before re-installing the moped sounding, power robbing insert.
