I agree it would be the catalytic converter. To be sure though since they are rather expensive it would be wise to hook it upto a diagnostic machine just to be sure.

What would cause the two exhaust manifold pipes on the passenger side to glow red hot the ones on the driver side does not get red hot 2000 Mitsubishi galant 2 4


Try checking for a restriction in the system. possibly the catalytic converter. are the pipes before the muffler? you can smack your catalytic converter with a dead blow hammer a few times before you start the engine. you will hear a sound similar to breaking glass from inside the converter it's carbon build up. Start the engine and rev it up a little. If it was constricted the carbon you broke loose will blow on out. If nothing is restricted in exhaust you may have a bad exhaust valve on that side.

Catilitic converter red hot now car wont start after its cooled 1996 cavilier


You should never drive a car with a red hot catalytic converter. If the catalytic converter is heater up to the point where it is that hot, it could be a serious fire hazard. Cars which might have a leak in a fuel line could be at a major risk for a fire or explosion if gas fumes come into contact with a catalytic converter in that condition. -----------------------------------------------------------------

2002 ford escape red hot exhaust spudders and rpms drops to almost stall


Carol Ann,
Your catalytic converter is plugged up [restricted] This is causing the exhaust to get red hot and causing the reduction in power. You need to replace this part [$$$} The catalytic converter failed because you have been driving the car for months with the fuel mixture excessively rich.
You need to find and fix the cause of the rich mixture or your replacement catalytic converter will also fail in a few more months.

the converter is what is restricting power from engine. causes of a bad converter are: decreased engine power, indicated by low rpms on the tach. hesitating or bucking during acceleration, the car will loose power going up a hill. if engine runs hotter then usual and coolant is up to par, it may indicate a bad converter. also black smoke from tail pipe is another indication of a bad converter. good- day!!

You could have a blocked catalytic converter. When engine is at operating temp, if the pipes glow red in the vicinity of the converter (enough to get the floor hot), it's critical to replace the catalytic converter to restore power and prevent engine damage.

Sounds like you have a plugged up catalytic converter. You cant clean them it will need replaced. If it is the 4cyl engine, the converter is the exhaust manifold on the front of the engine.
