You can probably remove the rusted pipes with a bit ofBTDT--what's happened is that the end of the tube is rusted to the manifold and to the tube nut at the bottom of the threads. When I try to remove the nuts, the tube starts to twist. I've used penetrating oil, heat, & a variety of words momma didn't teach me to try to get it loose. These are the original manifolds for the #s matching motor to the car, so I don't want to screw them up and have to buy new tubes (I'm cheap). The exhaust is all new from the head pipes to the tail pipes, & the *#%* muffler shop welded it all together, so that would be a real pain to modify. I'll keep looking until I find some that I know will work right.
heat and just
install some plugs to seal them and put it all back together. Ed
Thanks for the help.
