Vibrating exhaust

[olcoacher]

Hi, I am new. I own a 98 4wd XLT. Great machine!!! However, when I am stopped and the engine is under a load(sometimes not), my exhaust pipe begins to make a very annoying rattling/vibrating sound. It's somewhere in the exhaust. When I get underneath, I can stop it by pushing on it. I have tried wiring it in a bit tighter, but it comes back. Anyone have any ideas?
Should I just change it all? Or can I fix it? Thanks, Doug

it might be your catalytic converters, mind did the same thing rattled really nasty, so i took it to a local muffler show and got them cutt off and just replace them with a straight pipe, cost me $75 and stopped ratteling

one of your hangers might be broken. you can take it to a muffler shop and have them weld it back in place.
