smacked y-pipe now lots of rattle and vibrations

[Z28boy2000]

ive had my full exhaust set up for some time now and last night after filling up i went to turn around and my y-pipe smashed the the lid to the in ground tanks that hold the gas (like where the trucks hook up to fill the tanks) and on my way home my exhaust began to rattle and vibrate like no other.

i would have some minor banging on the floor boards but this is 100x worse and the car vibrates a whole hell of a lot worse now as well when im just driving around

any clues to what i should check to see what loosened up or why it is hitting the floorboards so hard now???

I'd get it up in the air and start at the front and work your way back checking everything. Something like this could be just about anywhere unfortunately.

My bigest worry with my exhaust is hitting something and damaging the headers or bolts attaching them to the block.

I'm praying that's not what I did

probably just bent something. Is everything past the headers bolted together with band clamps, ubolt style or welded?

its all band clamps from the headers to y-pipe then ubolts for the LM1
