Well to answer your questions, the mufflers are prolly equal to the stock system if not quieter! it is more mellow, but deff deff! not louder at all. Ive posted this on like 3 forums, everybody thinks its rediculous. yes it was a columbus local cop, obviously he was bored out of his mind sitting there clocking so he decided to have some fun and ticket me. this whole idea is crazy "all aftermarket exhaust systems are illegal!!!" pfff
