Has anyone used the OBX 98-00 Corolla header?

Alright, I did search, and only found a few people asking about this header, yet I found no feedback on quality and/or fitament. I have heard that OBX sucks, but even a blind squirl gets a nut every once in a while. Anyway that stock manifold is warped and as anyone who has one of these cars the manifold flange is the biggest piece of garbage and I don't really want to spend money on a manifold with a flange that is that thin unless I have no other good option.

I've heard a lot of people complain about OBX quality in general, I'd try finding something else instead.
