Exhaust leak... somewhere
 

I have an exhaust leak on my jimmy, somewhere, I am assuming where the exhaust manifolds meet the exhaust pipe, but not 100% sure. All I know, is its fairly "loud" even lough I like the sound, the exhaust smell when I have my AC on and sitting at a stop light inside the cabin is pretty annoying.
Any suggestions on this?

I have busted bolt. Right exhaust manifold forward bolt. Broke off in head. I don't want to mess with it till I get a set of headers.
