Sound Levels

[dopeyferree]

I have a Yamaha Raptor 660 with a Sport Series slip on. I plan on GNCC racing and I need to know what the sound levels are. Will it pass tech insp. or do I need to get a quiet core. Does anyone know db levels without quiet core and with quiet core.

The sport series on the raptor will run at about 104-105dbs and with the quiet core installed it will run at about 96-97dbs. Hope this helps.
