Why do headers glow red

Thanks for the reply Danny. You're exactly right! I had the wrong setting on my knock sensors and it was pulling a ton of timing. Andrewb70 seen this in my tune. I have the sensors turned off for now and this cured the red hot headers. Good stuff here guys. Thanks for putting this up Danny. Join Date Jun Posts I did the same thing also, LOL.

The main reason why a catalytic converter is a bright red is due to a cylinder misfire.

Other possibilities could be engine running rich, or fuel is not being burned completely inside the engine. What causes exhaust manifold overheating? There are several reasons that your exhaust manifold can overheat. It could be a timing issue, your catalytic converter could be stopped up, or you could be getting unburned fuel in it that is getting ignited and making them cherry red.

The reason the muffler is glowing red is because the exhaust temperature is off the chart. This highly likely means that the ignition timing is out, or the fuel mixture is too lean. Sure, one possibility is that it can be clogged. Another common reason why a catalytic converter glows red is that raw fuel is getting into the catalytic converter and is getting burned there.

For example, if you have a cylinder misfire due to a bad spark plug or ignition coil. To some extent, a clogged catalytic converter can somehow unclog itself. However, do not expect that it would be as clean as a whistle compared to using a cleaning solution to get rid of all the debris that has accumulated within the engine system, particularly after using the vehicle for a long time. Can the catalytic converter catch fire?

The short answer is no. Next, modern vehicles are tuned to run best with catalytic converters. Removing them can reduce your performance.
