Magnaflow Catalytic Converters...22644 or 51841?

Recently, I was looking into replacing my broken cat with a Magnaflow direct fit cat, since I don't have the tools to make welds/modifications, and I wanted to keep the car 100% legal. When I was looking at their products, I saw that there were basically 2 cats that seemed the exact same except for their price, $115 vs $230, and the fact that the $230 said it was "OE Grade OBD II" Whatever that means. I emailed Magnaflow, and this was their clarification response.

Hello Paul!

22644 is our standard aftermarket EPA compliant converter. As you noted 51841 is our OE grade.

From our website:

OEM Grade converters are specially formulated with a heavier wash coat and loaded with twice the amount of precious metals (platinum, palladium, rhodium) to provide a much stronger coverage.

OEM Grade is recommended for vehicles that have:

High Mileage
History of Check Engine Lights
Gross Polluters
California Emissions Equipment Outside of California

Please refer to your emissions tag located on the underside of the hood.

So from what it looks like, if you're looking for a standard direct fit catalytic converter, then both options are perfectly usable. The cheap one works the same as stock with regard to fit and sensor function.

You pay a lot more (relatively) for better catalyzing, but I can only imagine that this would create more of an obstruction and decrease power more than the cheap-o one.

I'll be installing the cheap one either today or tomorrow, hopefully, and I can give details on how well it seems to work.

(I had posted this question in DIY engine, since I was going to be replacing it myself, and that seemed the best place to put it, but I'm putting it here now for reference in case anyone has the same question.
