I have a 77 xl with swing arm and stock oil tank, with forward controls.

Im having some issues finding some decent pipes to fit this combo....What are you guys running and where did you get them (if you didnt make em)

speedway as some very reasonable "make your own kits" even if its 18ga....

but now, the question is, what is/are the best performance for a set of pipes....2 into 1's? 40" drags....shotguns?

I'm not going to baffle or muffler or any of that, but want to get some decent back pressure

any suggestions or time tested know-hows?

what is the preferred length to get to the "1" from 2....farther away or closer?
You're over thinking this. Just put the collector where it looks right to your eye and clears the controls. On a highly tuned motor with lots of cam overlap and a narrow power band the correct pipe length (or primary pipe length on a 2 into 1), diameter, and configuration can be critical. On a stock or lightly modified motor--- not so much. There isn't any pipe set up that's going to change the power, plus or minus, enough to worry about. It's an 'ol Ironhead, not a Hyabusa.:D

A 2-into-1 system, with some kind of baffling, will give you good overall street performance & rideability.
As far as length goes --- the headers, whether side-by-side or one stacked atop another, just need to clear all of your foot controls & kicker (if you've got one).
Mine slip into the collector just past the sprocket cover.
