polaris Posted December 19, 2022 Share Posted December 19, 2022 (edited) Hi, does anyone have any idea where the codes are on OEM 350Z cats? People keep asking me for the codes and I've got no clue, I've had a real thorough look and can't see them anywhere. Thanks Edited December 20, 2022 by polaris Quote Link to comment Share on other sites More sharing options...

I've put my OEM cats up for sale on Marketplace and I keep being asked 'What are the cat codes?'. I assume it's something to do with identifying the precious metals inside or something but I can't find any 'codes' stamped on the cats Do they differ from the actual part numbers? If not then I'm all sorted Edited December 20, 2022 by polaris 1 Quote Link to comment Share on other sites More sharing options...
Coz@TORQEN Posted December 20, 2022 Share Posted December 20, 2022 They are normally etched into the cats, it'll be under the heat shields if anywhere, they are codes to determine what metals are inside as you said (different to the Nissan part numbers). In my personal experience AMF Cats on Facebook has the best prices for a quick sale, sold 3/4 sets from personal cars and projects. Sure, you can get more on eBay by waiting it out but if you ship to them, they bank transfer the same day they receive them. He won't need the codes as we've sent him both 350z and 370z cats in the past so they already have what metals are inside on file. 1 1 Quote Link to comment Share on other sites More sharing options...

For future readers, the cat code can be found on the mounting bracket with the 2 bolts. I had to run some steel wool and emery cloth over mine to make the code visible.
