Thinking about logs

[o2camaross]

So I'm contemplating building my own log setup. I know I could buy a kit from trick or KB or from one of the members on here, and I still may but I just want to consider the options. This is going to be a budget build since I am in college still. I finally decided to pull the trigger after that hot rod article. I have a nice miller mig and shop at my disposal and I know the basics on fabrication I would say. So say I want to build a log, what material woul I use and where can I get it from? Where is a cheap yet reputable place to buy flanges from? And what kind of cost am I looking at? I don't want to do to stainless bc of the price and idk how I would weld it. I'm pretty confident I can copy the pictures of manifolds that I have seen here but is there any helpful tips that I can use? As for the crossover I plan to just buy pre-bent pipes but idk where to find the flex fitting at. Also my roommate thinks it would be better to not build a log setup but rather mount the turbo in front of the engine with the manifolds just swapped around? Any benefit to that design over a log design? I know it's a lot of questions but I'm just wanting to maybe do this myself to save money and bc it will be fun. Any help is appreciated.
