Cats below threshold?
I had Auto Zone check my SES light and it said both my cats were below threshold. What are my options other than replacing the cats? Can I run an ORY to the stock manifolds or do I have to have headers? I know I can just cut the cats off and weld a pipe in but it will still throw a code. I plan on putting LTs and an ORY on eventually so there's no need to buy cats now and throw them away in a few months.

before doing all that, try replacing your rear O2 sensors. i had that same code and that was my problem. on the other hand if you plan on doing LTs, you may as well get them tuned out.

I've replaced the 02s already. If I can run an ORY with the stock manifolds, that's the route I'm probably going to take but I need to know for sure before I try.

I have done fuel injection cleaning on cars and cleared trouble codes you are describing. expecially when they are direct fit converters costing 1200 dollars to install... The service runs around 100 dollars and benifits in many other ways, success rate for clearing converter codes is probably 75% or higher!

bingo, just as I said (Almost like I know what Im talking about) Another footnote on cats is that a Cat with VERY VERY RARELY go bad without an engine issue.. Rich condition, lean condition, burning antifreeze.. for it to either melt the cat, or contaminate it... furether investigation is required for proper repair... I know you didnt want to hear that.....

i am having the same issue, i have a scanner that shows live data. there is some tests you need to perform to determine what is throwing the code. i have not yet done this, but i will let you know how it turned out.
