Whoever you're talking to is phrasing it poorly. There's no qualitative difference between the two. The other part number is more heavily "loaded" for vehicles that have emissions issues that can't be tamed by a normally loaded converter. That other one won't flow as well either.
If the converter substrate is fragmenting, this is a quality control issue, not the result of it being "lesser" quality. Magnaflow should cover this under their warranty, especially since the part is on engineering hold for quality upgrades.
This is the email I got from them recently:
We are verifying the part on vehicle and it may take longer than that before it comes off Quality hold.

So you might try contacting that person since he's clearly aware the part is being held pending resolution of any issues.

I really dont know what to do here If i somehow get the 93241 again is it just gonna crap out in 10k miles or what? The better of the two is on backorder and was told maybe in a month but I was told they have 93241 ready to go...
