If i remember correctly, the area cat was thicker metal. Mig would do great on it.

I was motivated by the hope of a little better performance. I did notice a couple of mph on the top end consistantly afterwards. The cooler temps on my leg was a welcome outcome.

Yes.

A MIG would be easy for that project. If you have a Miller with infinite voltage control, it'll be painless. If your welder has four, five or six voltage selections, it'll take some trial and error.

A Lincoln Pro-MIG 175 (5 Voltage settings) & a Miller Diversion 165 TIG.

It'll be cake with your Lincoln.

Another thing you can do is shop for some DOM tubing that has an ID that matches the cat OD. That would allow you to sleeve the cat and have more material to weld, rather than splicing tube together.

Put another way, let's say the cat is 3" in length. Buy DOM tube that is the same length, cut the cat in the middle, gut both ends, slide the DOM over both ends and weld the ends of the DOM to the stock exhaust pipe. be sure to reference a horizontal line on the pipe before cutting, so that both ends bolt up when you're done.

Not trying to dumb it down for you, rather I'm trying to organize my very random thoughts.

On another note, I've had excellent results with brush-on flat black heat paint (Rustoleum in the US, Tremclad in Canada). I use a foam brush.
