Mufflers - From the tip to the canister has to be the same diameter. Under 3" and not widen at the tips. Aftermarket mufflers with some baffles are always louder than stock, but they can be under 83 decibels 1000,2000,3000 rpms. Any sound meters set "SLOW" on weighing "A" human ears vs "C" setting will be a lot higher.

The "A" weighted sound level discriminates against low frequencies, in a manner similar to the response of the ear. In this setting, the meter primarily measures in the 500 to 10,000 Hz range.

C Weighting is usually used for Peak measurements and also in some entertainment noise measurement, where the transmission of bass noise can be a problem
