It depends. If you live in a 'testing' state, you will have a problem. CA only allows OEM converters, quite expensive! Aftermarket cats are reasonably cheap, but only last for a few years. I would call junk yards for a used OEM version with 'low' mileage version.

In states with no inspections, you might want to install a rear O2 sensor extender. That takes the O2 sensor out of the exhaust stream so that the readings do not fluctuate.

It is quite possible that 'burning' antifreeze for 2 years clogged up the cat.
