OK. So either I need to tighten the bolts or I need to twist them off so I can fix an exhaust leak. Can anyone tell me if there's a good way to go about getting to the nuts? I didn't see a good way when we had it on the shop lift and I didn't see a good angle going in from the top. Any ideas?

 

Not sure where your looking but I've never had a problem on any of my bolts with a normal socket set or occasional spanner. I didn't even have any shear off which surprised me.

 

Do you mean the manifold to head bolts or manifold to y-pipe bolts? The bolts at the head can all be done up top, the two bolts from the manifold to the y-pipe have to be done from the bottom if I remember right, with a long extension.
