I know the design isnt very efficient but I did use 2" internal diamter pipe. I can make a "spiral" style equal length header but all it would really do is smooth out my lower rpm spool up and make it spool faster. Anyway back when I built this I had never even done a header before Now I have built 5 of the same ones and a couple equal length headers for friends hondas and nissans
