Cat Converter ?

I was going to buy a cat converter today, but then I realized I dont know what Im looking for, because all the ones i see are for off-road use only. Im looking for something high flow that will work great, and still be able to pass emissions. I need a 2" 1/4 inlet and a 2" 1/2 outlet. I check summitracing and they dont have any. ANyone know where I can get 1? The outlet also has to have the 3-hole flange. Thanks

If you are to pass emissions you will most likely need to get a stock replacement...

David-b, check out this discussion: http://www.dsmtuners.com/forums/showthread.php?t=178759
It has links to some sites that sell high flow catalytic converters plus a link to an eBay one. Hope that helps.

remember he still needs to pass emissions.....

So I cant get a high-flow cat then? I need a stock converter? Where can I get one of those? Muffler shop?

He should pass with a Hi-flow cat. If your state does the tailpipe test, verify that the cat is smog legal (most are). If your state only does the visual/OBD-II test you will be fine. Mine passed.

Are you sure? Seem to be getting mixed signals here. lol.

Would something like this work?

It says it's smog legal.

Does your state do the tailpipe test or the OBD-II/visual test?

I know they hook something up to the back, so its probably the tailpipe test. Looks like a vacuum hose. lol. So, I need to weld flanges on to something like that right? I see that you can buy the flanges seperatly.

Damn, Im a post whore now. lol

This is the exhuast I want to get: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7968218985&category=33630

Its got a 2 1/2 in pipe. My header got a 2 1/4in outlet. The downpipe has 2 flanges, and the catback has 3 flanges. There are no flanges on the converter tho. Whats up with that?

You can buy flanges for this one.

Also, do I need to buy a O2 sensor bung for the cat-back? Doesnt look like it has a space for it.
