Thanks for the replies guys, I should of said what spec I'll be running!
I'm building a KA with a 2.0 Zetec, very lightweight and basic breathing mods and cams for the time being, as we have a pipe bender and laser I figured we could make our own exhaust including the manifold, so at the very most, 150bhp for the time being which should be more than enough while I source some parts for a turbo conversion.
