Kooks green cats

That's what MAC suggests. There is room under there to cut it off with a Sawzall or a chain cutter. Mock up the exhaust pipe/flange, tack it and the tig the inside.

That 4xx steel is pretty hard to work with. It’s hard to cut with a saw due to hardness and work hardening, and I couldn’t imagine even trying to fit a recip saw in there to get a good square cut. FWIW it cuts easier with abrasives like a cutoff wheel. Then the remaining stub isn’t round and again, the material isnt easy to form. I know doing this job on a workbench is difficult due to the geometry and material properties. Doing it in situ just seems like needless torture.

Yes, I used a zip disc on an angle grinder to splice the Gsport cats into the 2M Fab pipes (3 inch 304 stainless). it definitely was a bitch cutting the tail pipes off with a sawzall for the x pipe and I think that is aluminized steel, but I could be wrong. Might be 409 stainless like everything else.
