C63 Edition 507 Stock Cats

Hi, this is my first thread on the forum and I recently purchased a 2015 C63 Edition 507. It turns out the car has cat deletes, which is fantastic. Unfortunately, it won’t pass smog in California and I can’t get it registered. I’m looking for stock cats for my car that will be cheaper than buying through Mercedes. Are the cats for the 507 the same as any other C63 or do I have to find cats specific to my car?

Thanks for the help,
Billy G

They’re the same. Which cats are deleted? Primary or secondary? Or both?

You need to see what you have, as the primary cats may not bolt up if the headers/exhaust manifolds were also replaced. Do you have an under car pic you can post?

I'm pretty sure the 507 shares the same exhaust setup as the standard and P31 models.

I’m gonna be able to get a pic of the underside today. I’ll post it once I have it.

I can't see any reason why I would swap back to stock.....dont want to deal with the header install ever again even even if I sell the car. Yea, I know I'll make more money converting to stock and selling parts....

With that said, I have stock manifolds and stock cats with pipes in my garage. Came off my 14 507 6 months ago with 20000 miles.

I suppose if you needed them and made a reasonable offer I could sell them. I'm in NY so obviously they need to be shipped

Edit...not sure if you need the secondary cats in California to pass smog but I have those also if you need them

We just put the car up and the cats were cut out and straight pipes were welded in. I’m taking it to a muffler shop to see if they can revert it back, but if not I might have to take you up on that offer.

How much might you want for the stock parts?

What exactly do you need?

Manifolds?
Primary cats with pipes?
Secondary cats?

All 3?

I have the resonator also if you need/want that
