Clogged , check the rest of your exhaust after cat to see if it gets hot

you can buy a no contact thermometer for less than $55.00

but the shop that installed the cat should have that

good luck

I have a Toyota quantum voting 2008 model the front pipe of the exhaust gets red hot within minutes and the exhaust bafflesystem burn out after a month or two this is the 3rd ex any ideas


Baffle system? When exhaust gets red hot, usually means your catalytic converter is clogged, but, ive seen instances where a muffler had gotten clogged and was doing the same thing! Aside from the, air/fuel mixture being off could also potentially cause this!

My Durango has a smell and gray smoke comes out the tail pipe when I start it


Check for computer error codes with an OBDII scan tool - it'll probably tell you that the catalytic converter is failing, but it won't also tell you that your engine is probably badly worn so you're seeing oil smoke - when the catalytic gets hot enough, it fully burns off the oil smoke so you won't see it any more. Meanwhile, your oil level is probably dropping pretty fast.

When my vectra been stood overnight lots and lots of white smoke come from the exhaust upon start up.any ideas


You're burning oil and it takes the catalytic converter a bit to start doing that for you. Something's come unsealed!
It's common enough; try to sort valve clearances and EGR/turbo obstructions by looking at the computer log, then if not sorted pick a date to pop the head and seals off and place seals anew. Nice car.

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. -----------------------------------------------------------------
