Rusty muffler flange - How to detach it

[Phantomphixer]

Thanks to everyone who took the time to respond. Several different options appear to have worked for others. I did find Dorman 03127 - exhaust stud kit, that looks promising but not metric. As I clean and prep for reassembly, I will settle on a solution for this. I have a lot to do before then; I pulled the exhaust, driveshaft, rear sub-frame assy, to repair a leaky tank. The things we do for love; but anyway, I will post whatever my solution Is to this problem. Thanks again!

Bumping this old thread. What was the solution ?

After much searching, I never did find the proper stud. It frustrated me because it is a simple splined stud. My old 1998 Jeep used a similar stud in its exhaust (unfortunately a different size). I ended up just using nuts and bolts. One thing I did do that I have not seen discussed is use a ball-joint press (the big C-clamp type) to remove the studs from the flange. It took a minute to figure out the set up but worked great. I preferred that to the grinding and drilling option. If you don’t have the tool, it might be available for free rental from your local auto parts store.
