under 400 isn't possible the Intercooler core itself runs about $300. It looks like arc used two different sizes of sc5 pipe equivalent and a bit of flat stock. all aluminum of course. then I have to buy wire, argon and weld consumables. i figure each one is about 5-6 hours of work for me with purge and fitment. materials and delivery I doubt my cost will be under 500. Im pretty sure it would be around $700-800
Im pretty sure the arc's ran 900 new and i'm sure their profit margin was higher due to bulk material orders.
my only other option would be to find a chinese manufacturer, then bulk, time, quality and morality come into question.
Id like to re-create a quality product that has been taken off the market, not a cheaply made knockoff.
