This^^ finally someone without builder envy and logic breaks it down. The premium price for the pipe I understand as the competition isn't much cheaper at all. It's the machine work cost that boggles my mind as there's only so much gain to be had from a port job and the majority of machinist use templates anyway so a port job is a port job is a port job basically.
PS what are you waiting on from powder coat? I'm waiting on ball joints and cushion arm bearings from Jason then its roller time.
