can't clean them.

have to be careful about buying used a used cat. Not because of the quality, but because it is actually illegal to sell them unless they are tested, pass standards, have a warranty and are labeled. Will anyone enforce it? No, but you dont want to be the test case either. lol

Finding one from a low mileage car would be best. FB market, CL, etc.

ROW tune could be a possibility but not sure how it would go with emission testing. Have seen people do it but never reported back if they actually had to do emission testing or not and if so, if it passed.
