Which long tube header that is not TTI suck the least?

for $500, just get a greneric header weld up kit and make them with the pieces. Get a chop saw and just start piecing them together with cuts. Tack weld the pieces together so you can break them apart easily and just build one pipe at a time. Take the finished pipe to a exhaust shop or some welding shop and have them finish weld them. you can separate the flange at the outboard pipes. Paying $800 for 8 bent pipes is not in my budget.
