I'm wondering if this is what is going on with the bimmer.

A plugged cat will also superheat because of the obstruction, causing eventual failure of the cat.

If your cat is glowing, that would be a sign of a problem...

I dont know if anyone rembers I did complain about the glowing cat. Myabe thats my problem
ok if someone chooses to remove the cat what is this cause?

A plugged cat can cause an awful sulfur/rotten egg smell.

A common cause of a plugged cat is running rich. The cat is designed to burn unburned fuel to reduce emissions. Too much unburned fuel overheats the cat and whatever's in there melts and plugs the cat.

The cat can also be plugged by oil in the exhaust.

If your car has an oxygen sensor, check it. Do a web search to see how a healthy O2 sensor displays on a VOM.

You should be able to swap your cat for a test pipe for diagnostic purposes. I don't know if it's legal for you to do so where you are on a temporary or permanent basis.

Well we are going to do the same thing we did to the s10 stick a pole in there and break it up to where it blows out the tail pipe. just figured on doing that because of the pain it would be to put a pipe in place of the CAT. any tips on breaking bolts that have been on there and rusted?
thanks

Well today My cat was exposed and I played around with it only to find one side is already gone and the other side seemed to be plugged. I drove the car about 20 miles and had no over heating problem just some very poor preformance. first gear is ok and the reast i had it pined and was bar;ey speeding up at 60mph it was and a dead end i had it pined for a mile and only got it up to 68. Still have the pre igniting problem though at idle so I have some way to go yet.
