I DONT KNOW FOR SURE BUT I DO KNOW THAT IF YOU DONT GET THE CAR REPAIRED YOU ARE INDANGER OF STARTING THE CAR ON FIRE THE CONVERTOR RUNS NORMAL AT 1500 DEG. WHEN IT GLOWS THERE IS A MAJOE PROBLE WITH THE ENGINE RUNNING TO RICH OR LEAN. PLAESE DRIVE THE CAR TO THE Hyundai DEALER NOW!!!!!!!!!!!! sounds like the convertor has colasped internally. Check with the dealer to see if it is still under warranty. On most cars the emissions systems carry a longer warranty than drivetrain parts. Do this now......if the metal is glowing it could spark a fuel line and then there would be a real problem.

What is the lifespan of a catalytic converter?
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.
Can replacing the flange gasket to exhaust manifold clear a p0420?
Not likely because: Code p0420 refers to a problem with your catalytic converter. The engine computer is able to test that converter by using an oxygen sensor before and after the converter. The computer can only test the converter under very specific driving conditions. If the computer determines that it is a good time to test the catalytic converter it will run the test. It compares the oxygen sensor readings in front of the converter to the readings behind the converter to see if the catalytic converter is functioning properly. If it is not functioning properly it will trigger a p0420. Sometimes if a catalytic converter is on the virge of failing it may fail one test and pass the next. This will cause your check engine light to come off and on every once in a while when the test is performed.
