Which one of these Magnaflow Catalytic Converters should I use for Magaflow's cat-back and why?

If you look at the descriptions, the only difference between the four is the pipe diameter. You just need to pick the one that fits the plumbing you've got.

Ahh ok, then should I try to match the stock piping before the cat, or the magnaflow cat-back?

2.25" is the size you need. I believe that there is only 1 cat, and one resonator.

ok, thanks saved! Any idea what gains, if any, I could expect from a high-flow cat?

Easier said than done when, a) I don't have jack stands, b) nor ramps, c) nor a floor jack, d) very little free time.This is why I come to you guys for advice.

A few points:o Saved and Dimtri are wrong! (sorry guys) On the base engine there are definitely TWO cats! (and I'm 95% sure it's ditto on the GT) One is right at the exit of the header and the other is a short distance downstream, followed by a resonator and finally the muffler. Take your Vibe to a friendly garage for an oil change and get them to let you take a brief walk under the hoist and check for yourself. o That said, it would be quite hard to change the first cat, as it is practically a part of the header. o Also, in many jurisidictions it is illegal to change out a functioning cat.o Lastly, before removing the factory part, you should seek some unbiased assurances that the replacement will actually flow better!
