Hi All, I was hoping to get some help with a part number. I have an 17 z06 with main cat delete. As part of the swap, I remove a couple studs to allow removal of the cat attached to the stock manifold. I replaced them with bolts but want to have studs to put back in if I ever swap back. I have looked for the part number on gmparts as well as numerous searches in the forums but haven’t found it yet. Anyone mind letting me know that part number? The ones I removed are messed up.

thank you in advance,
Bbgun

is it the same as the main cat pipe to the secondary cats?

17 or 07? 07, you're in the wrong spot. thats called a C6

Sorry Mikec7z. I corrected my post. It is a c7z0607.

I know this is old but I'm Looking for the same studs. I need the 4 studs on the bottom of the exhaust manifold where the cats bolt up

bbgun

I will look up what I bought.

I do not have the part number. I ended up going to my local chevy dealership for them.

its been awhile here but i wanted to share this information for anyone looking
i replaced the OEM lower exhaust manifold stud with ARP part number "ARP Stainless Steel Accessory Studs 400-8019"
i bought them on Summit
https://www.summitracing.com/parts/ARP-400-8019
comes with 8 studs, nuts and washers. I haven't had any issue since install. i did buy new gaskets when installing high flow cats

EDIT
just so there zero confusion
im talking about these

If youre talking about where the mid pipe connects to the primary cat pipe, these are what you want and theyre cheap. Worked for me on my Borla mid pipe install.
