damn, last night at the beach my car sounded rough like it was missing, so I went home and poped the hood, no noise, now on the way home from class my car sounds like a old volkswagan and BAM! big boom from under hood folowed by sumthin hitting the botom of the car all the way back? WTF? Its at the shop now, I dont have time to mess with it, its finals week now and I need to pass. I think it was a exasut leak and maybee one of my clamps fell off? I duno it kinda sounds like a open header, but it was to hot and car was to low to see.

damm, hope it's nothing major

You probably blew off the downpipe, esp if you have an HRC kit clamped onto the DP. I blew mine off a couple times till i tightened the U-bolt so much it stripped the threads. Hope you didn't damage anything, but you might need a new downstream 02 at the very least.
