Headers

Okay I'm sure this has been asked hundreds of times. But I'm gonna ask anyways. Since my manifolds are bound to crack eventually, I might as well do the JBA headers right? But what if I didn't want to do a catback, intake, and tuner along with them? Can I just put the headers on, and leave it at that? Nothing extra. I don't really care to make my truck fast or anything I just want the reliability of quality parts. But if I have to do all the rest, I won't complain. I'll just have to do some saving before I go on that financial adventure. Thoughts? Help? What did you do?
