i am in the exhaust business and build lots of headers/ turbo manifolds... i can appreciate the value of true hand fabricated long tubes, however, i cant pay someone to do something that i can do myself... i have a local company that can laser cut/ machine flanges for me, but if i can just buy them for a reasonable price, it will save me the trouble... also, i assume that no one builds one piece long tube headers because they wont physically fit in the car, or is there another reason... honestly, i would rather pull the tranny to not deal with the slip fit collector... thoughts, advice???
