the actual catalytic converter is inside of the heat shield, so anytime you see a heat shield you have a catalytic. i have never seen two catalytic converters on our past hyundais. maybe it's just luck.
i'm definitely not cutting that sexy Kspec/Maintec downpipe.
thanks for all of the responses folks. you guys help me direct my confidence and purchase.
on to the next question. the test pipe? does it function the same as a cat? and will it pass emissions? will an O2 Bung need to be welded onto the test pipe? And how much better is the test pipe than the high flow cat?

That looks like a straight pipe to me, not a cat. It certainly looks a lot like the straight pipe I have wink1.gif. I'd go for something like this: http://cgi.ebay.com/ebaymotors/ws/eBayISAP...sspagename=WDVW
Edit: bah, you edited your post! A test pipe does not function the same as a cat. A test pipe will make your car obnoxiously buzzy. It likely won't pass emissions.

nice find a_gut, i was looking at the same ebay seller. that converter looks to be the one i'm looking for however, it appears to be for off road or racing purpose only! what's the deal with that! the other ones i was looking at said the same. why would they be illegal?
hahah... so i hate buzz. i will stay away from test pipes. but aren't test pipes like resonators? i guess resonators give a more throaty sound.

Not in Cali because it costs a FORTUNE to get anything certified in california that is does not affect emissions. It could be the best cat in the world, but if you do not have cubic dollars to go through californias stringent testing program, you can't sell it there.
It is not like they test the pipe and go "ok, you can sell it here" They have to actually colllect the emissions that come out of it and weigh them against what is certified stock and against California's allowances. It is a long and demanding test that includes hot starts, cold starts, running for hours on end. It is a mess.
this is why you often see things like "for off-road use only" or "not legal for emissions in California"
