that 2 1/4 downtubes,2 1/2 intermediate pipe and 2 1/4 tails is perfect even on a modified SC like mine.The intermediate cross section is less than the downs or tails and that's ok.Any larger mid pipe would likely cause a decrease in low/mid torque which is where our cars run best.A 3" mid pipe probably would give slightly higher hp at the extreme top end but at the expense of losing the bottom which is where an SC is designed to run anyhow.Heads and cam are not top end hardware.So anyhow,I'm sure this will really stir things up but this is what Dynomax said.
