a steampipe manifold TIG welded will cost you around the $400 mark custom made to suit your application, possibly more if it's difficult to get at the turbo's location to jig the flanges up (eg turbo on firewall side of a 1zz...). I'd hate to think what CES would charge for a manifold after Shao told me the price of his "race pipe"

Needless to say, Shao went somewhere else when he got the second one made for his new car and was $150 better off

To make the manifold properly, the shop should have the car available so they can get the turbo position right so you have room for water and oil feed/return lines, and the inlet, outlet and dump pipes.
If you have a spare long motor and some photo's to go by, it's possible to get a decent item made out of the car, but you require a custom dump pipe and others so it's best to get them all done at once at the same shop.
