I need to put a cat on my car (the fumes are killing my wife LOL) and am wondering if anyone has an opinion on the Catco vs. Magnaflow vs. Walker cat?

vs.

and

To my eye, it looks like the Catco may flow best, but is there any proof one way or the other? I know Magnaflow has a good rep as well, and price-wise they're all pretty close. I just don't want to lose too much power.
BTW, these are all replacement '84-'85 Vette cats; overall length is the same and the flange is the same as my Monte, but they typically stay at 3" all the way through, instead of shrinking down to 2.5" like some Monte replacement cats.
