I just wanted to hear some of your opponions of this two piece manifold for a supercharged H22. The primaires are 1 3/4 inch, and then it goes straight into a 3 inch. Do you think you will see gains with this, or do you think you will lose to much low end? I did not include a picture of the bottom half, but all it is , is the rest of it which contines as 3 inch with a flex pipe and connects to exhaust piping.
