<strong> The great debate continues..... We use a 1 3/4" diameter pipe about 6" long, I picked it up for free at the local muffler shop (Midas). If any one flowing heads needs one I will send you one for free! We see about 30 cfm difference between pipe and no pipe. Our stock 1.55 exhaust valve has now seen 270cfm at .600". We ran our big exhaust program on a set of heads recently and installed the oversize seats and 1.600" Ferrea valves and it went 274 at .600" but the small port/stock valve outflowed it from .100"-.550". Pretty strange uh, this is not a car 1.55 valve, it comes in some truck heads, 4.8/5.3 it is very tulip in shape and has a big dish in the face of it. Phil, if you want a killer exhaust port then I would suggest a LS6 head, we have one that goes 280 cfm @ .600" and flows killer from top to bottom. I just installed a Stage 1.5 on my own C5 that flowed 270 @ .600", I want to run high 9's and I will let you know how it comes out.
