Hello I'm Grady, I have a 2013 luxury fwd xts I need a catalytic converter but I want it to be an OEM part. Is this one ???Grady M.Aug 08, 2022
Best Answer:Hi Grady, thank you for reaching out. This item isn't an OEM (original equipment manufacturer) part. It is usually the dealership that sells OEM parts. This item is an aftermarket, with OE (Original Equipment) specifications engineered to be exactly like the original OEM standards. This item is for models with the federal emissions 2013 Cadillac XTS Luxury. If this item matches your vehicle's emission system you can use this link to go back to the item page and continue the order: <a href="https://www.carparts.com/catalytic-converter/dorman/rb674048?can=CPAP3648_CSQA_20220808" target="_blank">https://www.carparts.com/catalytic-converter/dorman/rb674048?can=CPAP3648_CSQA_20220808</a> I hope this helps.

Customer Reviews

This was a perfect match for the original Chevy converter. Only thing different was the heat shield was not part of it. Upper metal gasket was the same but lower one was of a different material but certainly OK. The two bolts supplied for the lower flange were incorrect, but the original two I took out worked. Very happy. Recycled old unit and got $55 for it.
