Aftermarket Catalytic Converter Question

I did a search and can't really find the answer I'm looking for.

I have an 07 with 165000 miles and my tags are currently expired since I can't get it to pass emissions. It's throwing the p0430 code and a b165d code. I know people are aware of the p0430 code and that it's an issue with our JK's. The b165d code says"park lamp circuit high" and that's all I can seem to find about it.

I have a close friend who works at a little dealership and he had me bring it in to connect it to their diagnostic machine. They waived the charges for the diagnostic since my friend works there. It says that my cats are bad and that it doesn't say anything for the other code. I do have a rattle when I drive so I assumed they were bad before the diagnostic. They gave me an estimate and they're suggesting I go Mopar with the part.

So, do I go stock or aftermarket? I've heard from here and other boards that our JK's don't seem to like aftermarket for whatever reason. Is there any brand that can go with and save some money that will work? They want $1166 for the part.

Buy the part elsewhere or even from a lower mile totaled vehicle and have it installed elsewhere.

I have this same issue

but dont live in a state that requires proper emissions.

I was told a good muffler shop could weld a new after market Cat in, instead of buying the entire exhaust. Crown had the lowest price for that MOPAR part if I remember correctly.

Just to humor me & if you haven't done-so already, would you take a rubber mallet or your auto hammer ( or some type of hammer) out / under the Jeep & bang-on the cats 5-6 times each ( unless their diag yielded ID of which bank of sensors - i.e.- which side - it was) cat just hard-enough to not rupture or pierce or damage it but as hard as you can without doing damage.

nothin to lose by 3 minutes for that, huh?


( I assume also that OP found this & it's last comment from 01/07/2015? )
