I meant the rust one, not the rubber one :spin1:
Probably a good idea either way though. Got a spare header with a crack around? Bring it by sometime and I'll toss some sloppy ass welds on it, I did that to the one I put in my XJ 25k miles ago and it was still sealed up perfectly when I checked it Sunday with the motor out for repairs.
I'm not dead set on it being an exhaust leak, it doesn't sound quite right for one to me either, but I've heard some real clattery sounding exhaust leaks before and it's so much easier to check than engine internals so I'd look there first, being lazy.
