if you have mufflers, your almost certainly ok. if you have headers, no cats, and no mufflers, your almost certainly over and will need the baffles.
i have long tubes, no cats, factory resonators and race mufflers. im just under.
my car is loud, just not too loud lol.
one guy got his C7 to keep the flaps closed and he was fine. the C7s with headers and flaps open are too loud. FYI
