High flows are pretty much just smaller catalysts. The smaller the catalyst-the less it's like a regular cat and more like off road.

Tbh they're a waste of money. Any aftermarket catalytic converter (or none at all) is against federal law and you can be fined up to $10,000. Either go O/R or stock cats.

I don't have emissions checks where I live, but I might sound dumb here but what does o/r mean

Because it's illegal for them to do so on a street vehicle.

they are a waste of money and can be damaging to your car

when we were building mine for SEMA, one of the most major
exhaust companies basically told me not to bother with them

if I wanted it so bad, j was told I would be better off just going cat-less

In the past when ive had a car with a gutted converter I grabbed a few 18mm spark plug non fowlers. Drill out the "inside" of the non fowlers so your downstream o2 will thread into it, then thread the non fowler into the pipe. Kills the CEL for any obd style emissions test.
