Zare,

Could you give some indication of what you want from the engine and what you intend to use it for?

There are some ideas here:

"fast" (as much as it can be) street car. the ideas from Wolf Direct Racing, halped me a lot. i`m interesting what will i get with 4-2-1 exhaust mainfold like on the site, and any mesurements or dravings of the same...

A 4-1 exhaust tends to give optimal power over a narrow range while a 4-2-1 is usually configured to give a broader range of power - far more useful for rally and more likely to aid the longevity of the engine.

I don't have the dimensions you need - the exhaust you saw was bought in. We have plans to produce similar manifolds early next year in stainless steel.
