if it happens when it rains its normal cause almost every aftermarket exhaust rattles from what i hear, but when i first put on my skunk 2 exhaust it rattled like crazy against the frame like 10 inches from the cat...so i just had my friend heat it up and bend it down and it hasnt rattled at all since, a little when it rains tho
