You will only be able to replace this with the solid one piece 4 cat Y pipe. I just did mine. Got the OEM from Rock Auto which was the cheapest but I'm in CA. If you are in a emission friendly state this will be much cheaper.

I double checked this morning and I was mistaken, I only have one cat on each side. I'm looking at a walker y pipe and a magnaflow set. Not sure which one yet. I also read a spark plug non fouler will stop the CEL

If you are getting the code, the CAT is the only way to fix the issue long term. If you just need to pass emissions one more time, then you can try the other stuff. I waited 2 years and then mine got stolen. My gas milage with a new CAT is out of this world. I should have never waited.
