My son races Harescrambles/Deasert, so we need a sparky and 96db sound level. I have a FMF power core slip on for our '07 KX450F. It's consistantly testing at 99db, and the quiet insert makes it run poorly. I am looking at other slip on alternatives. Anyone have experience with the Pro Circuit Type 496. Again I need a sparky and 96db without killing all the power.
