So i tightened it, the sound is better but still there. I looked under the car, and from the top of the car. I can hear a whooooooooshh sound like that of an air compressor that is letting out air slowly. I went to the back. my tail pipe is vibrating and kinda makeing a slight poof poof poof sound, i barely put my hand over the, the pipe virbrates a little worse and the Poof PooF sound gets a bit more dominant.
What does this mean?

Sill patiently waiting for help
Check what we already told you to check. Jack up the car and see if you can feel the air leaking from anywhere in the exhaust. Check the heat shield on the cat.

get closer. put your hand closer and closer.
when my exhaust first started falling to shit I could hear it but I couldn't tell where it was from. there was a few pin holes on the top of the exhaust pipe in an odd corner. I couldn't tell exactly where it was till I burned my hand and put it over the top of the pipe.
I already had a good bit of dirt on my hands from being under there so it didn't really burn that bad, but it was useless cause the whole exhaust jsut kept going down hill each time I'd start it from there.

Well my whole system was shot, rusted, falling appart. So I replaced everything from the exhaust gasket on the block allllll the way back.
