Default Eliminating The Cat

My camaro hasn't been running all that great lately, as some of you may have found out through my other post...

I am tossing around the idea of eliminating the cat for a couple reasons...
1. Let the engine breath better
2. Eliminate it as one of my possible problemss

What would I do about the system that injects air into the cat?

Cork off that tube that connects to the cat.
That stuff kinda "fell off" when I had my 91.

So would it be safe to remove the entire air pump as well? Just leave the air check valves on the lines to the manifolds as they will prevent an exhaust leak from them?

Just re-read my post, I wasn't referring to the Smog Pump, I was referring to the distribution valve (don't know what the actual name of it is), but removing it would leave the line from the smog pump open, requiring me to get a delete pulley. Just need to take the line to the cat and cork it off like you had said.

Now, the trouble with that is going to be finding a shop around here (in california) that will weld a pipe in place of the cat. That will be the hard part.

Being in Californi, doesn't your car need to get emissions tested? Without a cat on the car, it will fail.

The county that I am in requires a smog inspection for the first original registration, then never again after that. I know, its a beautiful thing right? :-)

Average Cat gets clogged from carbon by 140-160k miles. How many miles are you at on that cat? is it stock? you may have to much back pressure

Only 60,000 miles on the car. But the previous owner ran it for 50,000 miles on LEADED fuel. Leaded fuel would be a nightmare for the cat, so it very well may be a contributing factor to my engine problems.
