The pic ain't very good, is it? Hard to see it, but it does look collapsed right at the end there. Do you know if those are the
original, factory pipes, or have they been replaced somewhere down the line?
The L82 engine should have had the 2 1/2" manifolds, AND 2 1/2" pipes all the way out. The pic looks like you have the 2 1/2" manifold, with a neck-down(on the pipe) to 2" about 8" from the manifold, which is the way the L48 was....strange.
I have actually seen exhaust pipes separate and collapse like that...usually and indication of a couple of issues, one being late(retarded) ign timing, and Chinese pipes...
Can't say I've ever seen it on factory stuff, tho, but it's totally possible.
