I replaced my transmission and I am gutting the cat before I put the exhaust back. I have ground the weld off of the downstream side of the cat so I am just going to weld that side back to the cat housing. The upstream side I cut, I wanted to install a flange and make it so I can bolt it back together instead of having it welded together. Anyone know where I might be able to track down fitting to weld onto the exhaust? It is stainless so I would need them to be stainless also.

I am wondering if this is worth $100. I tried pricing out flat flanges which are going to run about $60 and will need to be installed more precise in terms of angle to make them the bolt holes line up. I have a TIG so I can do the welding myself.
