get magnaflows they're not expensive and better performance. when i got all three magnaflow cats with installation it cost me about 600. later i found them for about 100 or less on ebay. i'd pick em up there. then just have a muffler shop install them. shouldn't cost you that much.

If you take a look at the Magnaflows, get a 3 way about .5 inch bigger than your current exhaust pipe.
Even with out precats on mine and just a Magnaflow, not a single check engine light. I even tested down here on a gas analyzer and it would pass the stringent requirements we have down here.
However, I am a Florida vehicle...no emissions and no state inspections...hooray.

I have friends down here who do this, and only in extremely high boost or high power applications is there any real gain. The rest I claim do it for show and just put it back in for emissions (every 6 months here).
Best to get a high flow as I mentioned before and be done with it.

Long article, but the guts of it are such:
- '02 Corvette Z06 exhaust if upgraded
- Dyno is performed with Random Technologies' high flow cats
- Dyno is performed without cats
w/ cats: +44rwhp, +46.8ft*lb
w/o cats: +44.7rwhp, +46.9ft*lb

Personally, I will risk my 0.7hp and 0.1ft*lb at the expense of not having the risk of getting thrown in jail for having no cats. The right cats flow nearly as well as a straight pipe.
