I'm wanting to ditch my OLD low hanging headers, are these manifolds worth it?

Hard to put a number on it, but how is that top manifold going to have anywhere near as good of flow as a header? And they won’t be as good as HP manifolds either.

how high do you rev the engine. How do you drive? 1/4 throttle put putting? Or stop light Grand Prix?

I figured that they would be more restrictive. As far as driving style....I'm usually somewhere in between Put Put & Grand Prix with an occasional generous application of the go pedal. Once I get the trans slip issue resolved I'd like to be more Grand Prix leaning :thumbsup:
