Well this integra is just a beater, that I'm getting tired of driving it stock. So I do want a little more power out of it. But I do not want to change where the Power is made (in the powerband)
I am looking at Cams but only a Cower Stage 1, this Cam adds a little more power but should not change the shape of the Curve. So with that mind frame, I feel the stock LS manifold will serve me better. Same reason why i got a 4-2-1 header, rather than shoping for a 4-1 with a big collector.
The stock LS mani is perfect with its long runners for low end power, but sucks at the top. But I am not racing this thing just driving from light to light, so just want to improve it where i drive it (low rpms). A new mani fold will give more power overall, but hurt my low.
So getting it honed will improve flow of air, but does not change where my power is being made.
