My son had a bad cat converter back in July 2017. So, I purchased one from a online parts store for $189. This included the pipes. Then first of November the CEL came on. He got the code read it was a PO420 bad catalytic converter. He had it checked at two other repair shop they said the same thing. My son came across cat converter on AAP website and purchased at the store. Yesterday, I took it to a local muffler shop to get the existing cat cut off and this new one welded on for $54 dollars. I drove it back home the CEL was out and the car drove fine. I hope that this one well last a lot longer then the last one. If not, he is glad that it comes with a warranty. So far, it's doing what it suppose to be doing.

Good product but very little room for error when cutting off old catalytic converter and matching up to new.

There is no hole for the O2 sensor, so this is not direct fit...installing this will cause a check engine light since you cannot reinstall the O2 sensor. It will not pass any emissions tests for the same reason.
Bottom Line not recommended
