The trick here is to get the nuts glowing orange hot with a torch, and they will come off easily. Exhaust heat won't do it.

Probably not, you need an oxy acetylene torch.

You might be able to do it with the Benz-o-manic if you get a cylinder of mapp gas for it. It will be the yellow cylinder not the blue propane one. The mapp gas burns hotter than propane.

Pop the manifolds off and take em to a muffler shop and get em to put new studs in.

Then when you put it back together, use a little copper anti-seize and stainless steel nuts.

Re: Exhaust Cross Over Pipe Removal ?

Taking the manifolds off can be a major paint in the behind, the french locks will all be rusted, the nuts probably ruste to the studs so you will tear up the heat shields with the stuf spinning... major PITA!!
