CUSTOM MANIFOLDS
Steel manifold is difficult to make. You need to form steel to ovals to round to tapered out. When used with a turbocharger, Steel won't break and would be ported to your cylinder head.

- Steel manifold for maybe $250 for Weber 40s or 45s. ** They also do nice head work for around $300 which includes porting and 1600 exhaust valves
Aftermarket manifold finish quality can be really poor so check for flat flanges, port overlap. See Jason's Weber page.
