Wow, alot higher than I was thinking.
No wonder the stove paint burns off.
That's more of a curing temperature for it than a sustained one.
Thanks for taking the time to do that!
Now lets see how close the other engine's run.

 

Just an FYI, I'm also running really rich. I have no idea why. The CEL isnt on and at this point, not gonna fix it because ..... see my signature.!

 

Does this help

 

Yeah, as suspected...they get Really hot, lol.
Thanks

 

So whatcha gonna do? Just deal with ugly looking headers?

 

Yep
The ugly never bothered me, it was the rust.
But, oh well, it's not worth doing.
I have read alot more on ceramic and catalytic converters, and they don't work well together.
