Inspection Problems...exhaust

any1 here got inspection problems for their custom exhaust? any ideas on how to get a sticker because i tried 2 places today in MASS. where the inspector got in my car and started it up and told me theres no way im passing you because its too loud...like what the fuck its ok to drive a harley that sounds like a plane but u cant drive a grand prix with a custom exhaust which sounds 10 times lower??!?!?
