Magnaflow catback help

[07PPVTahoe]

I bought the magnaflow catback system number 16672. Can anyone help point me to the right bolts to replace if I have to, and does it have a gasket? Autozone or rockauto is just showing me exhaust manifold bolts and I'm having trouble looking while at work. I'd like to install after as it just arrived. System I got

Oh? I called magnaflow and they said it didn't come with bolts or a gasket

That's odd as their own website shows them! Ok, the instructions say to use the OE bolts to connect the exhaust system to the y-pipe. Is this what you mean?

If so, I am not 100% sure as my exhaust uses a clamp in that position. My trucks are newer and show that they are M10 x 1.5 and could be 11547135 and if a stud it would be 11589264 and the nut for both is 15032594. Double check in case I made a mistake, my wife tells me I'm not perfect!

Yes I'm wondering what the oe bolts are incase I have to replace

These are what I'm talking about

Looks like there's enough bolt end sticking out to measure the diameter with a caliper, and take a paper imprint of the (lightly lubed) threads to measure pitch. Easy enough to estimate the length, which isn't critical.

You're gonna wanna PB Blaster those bolts for a few days before you try to run them out.

First and last part numbers I gave you if nut and bolt.

Thanks guys, I ended up just cutting the bolts, they snapped immediately even tho I've soaked with PB. Got grade 8 bolts nuts and lock washers and installed the catback no issues otherwise. At the dyno tune right now. Thanks!!
