Third gen exhaust manifold question

[jaboyjay]

Okay. Sorry if this is a new guy thread I really don't know how this works. But I have a break in my manifold near the head I'm just going to replace the factory manifold with one I found online it is an Ebay product so I am nervous about purchasing. I attached a picture I was wondering if anyone else had purchased this I've been searching threads to see. But couldn't find anything. Wondering if I should go for it and save money or just go OEM. I also have a broken stud inside the head when I change the manifold I'm going to get it out. Has anyone else had this issue?
