Why is my manifold getting hot?
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.
Will a clogged catalytic converter glow red?
Why is my Catalytic Converter Red/Hot? 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.

Is it normal for an exhaust manifold to glow?
I seriously doubt that red-hot exhaust manifolds are ever normal. Most of the time when a part of the exhaust system gets hot enough to glow like this, there’s a restriction somewhere. Does it have any other issues besides running hot, such as rough running or sputtering?
Can a red hot exhaust manifold start a fire?
ANY red hot ANYTHING under your hood is going to start a fire, sooner or later. I’d bet on sooner. And of course, even without the car burning to a crisp, you’re polluting the air. If it was mine, I’d get it fixed today. ok4450 July 5, 2016, 8:18pm #5 Often this is caused by a clogged or partially clogged catalytic converter.
Why does my lawn tractor exhaust glow red?
Or if the timing key has cracked and the ignition takes place a little too late then the charge will still be burning when it enters the muffler so will make it glow red hot. Once the muffler gets really red, it will start to burn itself, making the metal thinner and that will make the ehaust glow even hotter in a self feeding loop.
