Hey guys! So, I’ve recently had BOTH upper catalytic converters fail in my car. They disintegrated, and clogged the lower ones solid. Now, I’m looking to replace both upper cats only since the O2 sensors are only on the first ones, and I don’t live in CA.

does anyone know where I can get the passenger side one for less than $2,000 from? eBay I can get the drivers side for ~$200, but I cannot find the passenger one for the life of me. I’m also not afraid of used parts.

I have a 2015 ATS Performance 3.6L (N/A) Coupe (no PZEV) with 130,000 miles.

also, does anyone know if they use the same cats as the 4 cylinder models, or other models at all? I’ve found a couple contenders but they were all for the 4 cylinder ones or the XTS.

thanks ahead of time!!
