It s illegal to remove a catalytic converter.

Your car will not run better and you will get no better mileage. In fact you car will not run correctly without the converter as the ECU will not be able to adjust the correct fuel/air mixture properly without the converter on place. Know that is illegal in all 50 states to remove a catalytic converter. The fine is from $2,500 to $25,000.
Any Vehicle In most parts of Canada and Usa does not need to have a Catalytic Converter If it was made Jan 1,1995 and earlier.It will flow better and probably get more powerand mileage
Many of the compounds that make your engine oil work better on the INSIDE of the engine are also "poisonous" to your catalytic converter as your engine starts to use oil. The nice thing about catalytic converters, they burn unused hydrocarbons that come out the exhaust. You may not KNOW that your engine is burning oil until the catalytic converter gives out or even gets plugged up. Watch the oil level in the crankcase. If it drops with no evidence of leaking, it's burning and your catalytic converter will die.
No your car will infact run better (more power), exhaust gasses are able to flow much more freely without a Cat. The downside you will shorten the life of everyone who drives behind you as a Catalytic Converter Converts deady gases to less harmful gases. Highly Illeagal to remove these from you car. Fines in Australia are something in the order of $10,000.
Direct to fit Catalytic Converters come ready to install with all parts pre-welded. These are better for the DIY professional. Universal converters are cheaper, but require cutting, welding, etc. These installations are best left for the shop professionals.
One of the easiest ways would be smashing tossing the catalytic converter around enough to make the ceramic material break into small enough pieces to fall out. I assume the only reason to do this is to eliminate exhaust back flow for better performance.
You could, but the check engine light will turn on and the car will not run any better.
Could you, yes. Is it legal, no. Will the van run better, no.
Whatever kind of catalytic converter (or even none at all) the car was originally manufactured with is grandfathered in and does not have to be replaced with better ones as the emissions rules become more restrictive.
