1998 Chevrolet Tahoe - removing catalytic converters

If I remove the catalytic converters will my Tahoe run better or worse?

There is a Federal law that you will violate and you don’t even want to do that.

No change. It won’t run better OR worse but you will violate federal law!

Modern cats flow very well and don’t restrict power. And they clean the exhaust so all of us can breath a little better.
