Just a quick thought, did you put thread sealant on the front and rear bolts for the headers? If not this might be a good time to do that, they go into water!
It seems to me that this will have to come apart more than a normal exhaust car so when I get the other bolts, I was going to put anti seize on all of them.
No, i didn't know that. Thanks. Would plumber's tape be ok or should I pick up some from NAPA tomorrow ?
