Good. After putting it back together, the one on the crosspipe rattles like hell at 3,000 rpm now that half of it's fasteners have turned back to iron ore.

That's what I was thinking, but I went over the manifolds and crosspipe like crazy searching for cracks or breaks. I don't feel anything coming out except between the flanges. I suppose there could be a crack higher in the uppipe and the exhaust is just getting trapped in the heat shield and coming out at the bottom, fooling me into thinking it is coming out the flange. I haven't taken the uppipe off yet. I'm changing motor mounts soon so I guess I'll do that at the same time.
