catalytic converter

[josh760]

Hi my name is Joshua I have an 04 yukon xl I live in California, well my catalytic converter needs to be replaced. Im looking to see if there is a reliable and cheap site that has CARB legal cats the shop in my town says its a dealer item only and it will probably cost $800 I'm hoping i can find one cheaper and maybe aftermarket. Thank you for your help! also its a 1500 with the 5.3 and has two converters

this looks like it will be a tough find. all i can find are cats that arent legal for calif.

Since you live in comufornia its gonna be hard. Believe magnaflow has a carb legal cat but not sure

Magnaflow cats are only 49 state and Canada legal. I wish Cali would just go away. Or maybe it's ridiculous emission laws anyhow.

 

[Gzes]

Na I'd rather cali float away

 

[josh760]

I totally agree with the california ridiculous lol

Wrong...

Magnaflow has 2 sections to it's catalytic replacements....one is 49 state & one is California only.

Catalytic change + oxygen sensor

HI Josh -

I'd be interested in knowing if you found anything new out on your cat change.

I've got a 2002 Yukon XL (in California) that I'm trying to sell, and have to have it smogged before selling (state law). Factory installed system runs $2400-2700. Ouch. My alternate route involved having the cats on teh right bank cut out and the pieces replaced:

- Cat #1 changed first. Service light came back on.
- Cat #2 changed... service light back on.
- Now the service light is back on and says the oxygen sensor on the right needs to be replaced... another $350. (Compared to the factory replacement for the whole cat system at $2700, I guess this is better.) But there's no guarantee that the oxygen sensors will do the trick either.

How hard is it to change the oxygen sensor? The part seems relatively inexpensive, but I'm no mechanic.

I ended up going to an exhaust place in town and replaced all of them and he charged 1300

HOLY SHIT! I would have just ordered or found a new or used factory Y-pipe with the cats intact.

Cats!

How do you know if your CATS are plugged and need replacing?

 

[melmikulak]

CAT not the problem - computer was!

Ugh - so after spending about $1500+ on trying to get my damn CATs to work so I could smog my Yukon, we figured out it wasn't the CATs at all... the problem was a $100 part in the computer system that was reading everything incorrectly.

Something to consider when this falls your way.

Hey guys- new to the forum here but I'm bumping this up from the dead because I need cats for 07 Yukon Denali.

They started rattling a few weeks and now sound like shit and are embarrassing...I'm in California BTW.

Any advice on which ones to get for my application? They must be CARB legal. If this has been covered let me know, I tried searching the forum as well.

Thanks

No aftermarket oem direct fit CARB available. Magnaflow makes a pair of universal fit that can be installed in place of the existing pair via cut and weld on the existing y pipe.

Check Flowmaster Mufflers.

Get underneath and make sure it's not a heat shield that has popped loose. Seen it time and time again... just don't want you to dish out any cash you don't need to.

The shields hug the cats very snug on the top side so don't think you don't have them.
