stainless steel vs aluminized steel, mandrel bent vs regular bent

From what I hear, the super comps are the hot setup aside from TTIs because (at least on e bodies) they dont hang too low and they dont need the tie rod to go thru them, they dont capture the starter and you can still get to all the plugs....

Right now, the cost is the main issue.....Was thinking I would go with an exhaust fitted to stock headpipes and then later go to headers......that shouldnt be too costly to change later...I may even be abel to do that myself I figured....

I was considering a kit....but again, its the tie-in that is the issue for me.

If I know I would gain something and not lose power with headers, would go that route.....
