So I took my Mark to a custom exhaust guy yesterday. It was great finally getting to see the belly of this beast for the first time. We first decided on what it would take to tackle everything from the cats back. His plan is to cut off each pipe leading from the cats just before they will start into my XX pipes in the center. On the other side it'll start up with 2.5" tubing, welded together down that tight run, and split up both going into my UltraFlow SS mufflers. He said the cost for labor to do that much will be 250.
Now we decided to figure what would be needed to get the old cats replaced with high flow ones. At first he said it couldn't be done because the one was welded on. But I told him people have had them replaced before. He came to the conclusion that to fix a new cat to the left manifold he would have to completely remove the manifold, and bring it to a workbench where he would mold a new pipe to it since its some odd misshapen oval/square connection right now. The labor for that whole job natural would cost about 500. I can understand since the manifold would get detached, but you know, why not just new headers while were at it?
Well nobody makes headers for our cars so I'm trying to look into a tool that we could ram into the manifold to make its pipe a cirle, for easy welding, without having to remove it. Would this damage anything? Is there a specific tool designed for this purpose? Please, give me your thoughts and suggestions on how to fix this!
Thanks,

The labor to get into that area is going to be about 500. I'm paying 550 for everything UP to the cats, including parts.
