has anyone here or know of anyone who has tested there honda/acura with a decibel meter? i am tryin to figure out if i am actually over the limit.

i think the legal limit for a car is 87 decibel. my shit isnt even that loud and i have got pulled over 2 times in the last week for this shit. i have no cat and i have a normal flowmaster muffler 40 or 50 series with a normal tip. its not the huge fart can that sounds like someone is weed wacking they grass

however everytime i ask them to test it for me they just tell me to leave.
i know they dont carry that shit in they car so to avoid the tickets i just ask them to test it. but its still dick, i mean i live across the street from a cop and he never ever said shit to me over the last 2 years.
