Cat glowing red! Normal?
Hey folks got a question. Just had my FD rebuilt, large streetport, Power FC running on base map. Got a new Random Tech metal cat too and I saw today the bulge where the converter piece is was glowing red hot after idling for several minutes. Is this normal? I know they tend to run a little rich after rebuild but WTF?

Glowing red after a few minutes of idle is not normal. You could have a leaking fuel injector. Unburnt fuel makes its way to the cat and burns off there.

Well the random cat I got is metallic substrate like Knightsports. I suspect since the car is a very fresh rebuild that it is running pig rich. I am thinking just get ebay midpipe until I can break it in and tune it. It is running on base mod map that came with Power FC. Wideband also on the way. Damn

The cat shouldn't glow. EGTs shouldn't be that high that far downstream. You are going to damage the cat if you keep running it like that. Get the car tuned or find the source of problem. If you have an airpump you can try unplugging it temporarily to see if it helps. It is normal however, for the downpipe and turbine housing to glow slightly after spirited driving.

Yeah I wouldn't be freaked if I had been driving the hell out of it. But I was just idling trying to let the Power FC learn the idle. I know during breakin motors can run rich and I had my DP and exhaust manifold ceramic coated so all the heat is also making it's way down to the converter brick which is the only real restriction point. Just sucks.
