The Vic Jr. Manifold is a single plane design, more suited to high rpm running and lousy at low end performance and probably has lousy street manners.

A good dual plane manifold like the Air Gap, Weiand Stealth, or one of the cheaper copies will give you more low end with a slight drop off at the higher rpm's you're probably not getting into anyway.

I don't know if the Weiand Stealth is available from the factory this way, but I bought a used one with the Endurashine finish on it and it is really nice.
