It would be plain stupid to remove the converter. The converter is designed into the engine controls of the vehicle. Removing it wouldn't really increase power because they have very little backpressure. If you want to remove it because its plugged or bad then you could do so but the check engine light would come on and it would never pass a smog test. It won't physically hurt the engine to remove it. Removing the converter is against the law. I would have an aftermarket converter welded in to replace your old one if its bad.

Would a bad Cadillac converter make your van spit and sputter?

The ideal exhaust has no unburned gas in it. Since this hardly happens, a system to clean up air pollution was created. On the exhaust stroke of your engine, unburned fuel is forced out of your cylinder by the piston. That unburned fuel then makes it's way to the catalytic* converter. The catalytic converter basically gets hot to burn your unburned fuel and puts out the combustionally correct gasses. It is possible that your catalytic converter is the reason your van is spit and sputtering, but there are also many other reasons this could occur such as: timing vacuum fuel pressure air spark Signs that it could be your catalytic converter include: abnormally loud converter abnormally shaky converter hope this is somewhat helpful

What is the average life span of a catalytic converter?

Assuming the engine is tuned correctly and there is a minimal amount of unburned fuel reaching the converter, it should last as long as the car itself.

If this happens the check engine or MIL light will flash when the converter is being ruined.
