catalytic converter

[Chiggy]

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?

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.
