Hello

I am trying to get a 50 state 2005 tC to smog in California.

Car has Injen SS mufflers with one Cat up front.

Do the Calif tC's need to use two catalytic converters : up front and in the muffler?

If just one is enough and I need a new one will a universal one work?

Such as : ww.autopartswarehouse.com/shop_parts/catalytic_converter/scion/tc.html

If not, where may I buy a used one?

Thank you for any tips and suggestions.

Pretty sure you need one in the exhaust manifold, and one in the midpipe.

Must have 2, if its modified in any way its not legal in CA =/ (as far as amount of Cats and where they are located)

Find out the specs of the Cat from Toyota whichever one you need and then go to a muffler shop get a exact duplicate have it put in the same spot your good.

The listed exhaust on the car is a Cat back, meaning it should bolt up right at, or just after the secondary Cat. If you have only one, then the car likely has an aftermarket S-Pipe installed. There is no Cat in the muffler, learn your car.
If you need 2 Cats, get a second one welded before the 2nd O2 sensor and call it done.

All this information would have been found in a Search of your local laws, and SL with proper English skills.

Learn your car as well. what does the S-Pipe have to do with any cat?, sure OEM has a coke bottle shape. 1 on header, and 2nd on midpipe.

Information still holds true. 2 Cats are needed, you can weld one up. And a lot of people confuse the long slender resonator for a Cat, it is not. And "my car" isn't a Scion, and the last time I looked under one to give a crap was 1 year ago.

Hmm.

Any one other than Spicy_McHaggiz:

If its the first Cat that needs replacing what are the options?

Images indicate that its welded to the manifold headers. And 49 State ones run around $360.00

All I can find are 49 state ones.

Does any one make one that's aftermarket for 50 States?

Dezod just came out with a really nice aftermarket header with a cat in it you should be able to find it in the forums it just came out not long ago. makes good power and still has the initial cat looking to get one myself here soon.

Heres a pic of it i just found

Your only options are to get an OE header(PPC/Ebay), or find a crooked smog station. None of the aftermarket headers are CARB legal. END THREAD

Do you have the original exhaust manifold or an aftermarket header? You only mentioned "one up front". Sounds like up front is manifold... If so make friends with someone that has an original mid pipe that could let you borrow it to pass smog.

Maybe take pics of what you have? Idk.

THanks MixD

But Dezod says its 49 state only.

I cant find anyone that offers an aftermarket one thats 50 State.

Made from 304 SS runners in a proven 4-1 merge collector design, the Dezod Motorsports is an excellent edition to your 2AZFE engine. The Dezod 4-1 header offers a 49 state legal ultra high flow cat, which no other header on the market offers, and solid American made craftsmanship.

You are correct sir.

How do I know if the used OEM is good?

Do they go bad?

"CRAIGSLIST" i've seen them for $50. so~cal is flooded with salvaged tc's, so junkyards have stockpiles. what county are you in? california is big for under the table smogs.

I'm not sure how you'd check if the cat is good while off the car, I'd get the lowest mileage you could find for your best odds.

Yes, they do go bad. Running too rich can leave deposits on the honeycomb and burn giving the ECU misreads resulting in a CEL, which equals failed smog.
