4" IC pipes those look good Dan!! My IC pipes are 3.5" I do not think 4" would have fit as good!

Looking good cant wait to see them done and polished!

3.5" ic pipes are inefficient. dans ic pipes are 3" .

I know I can't be the only one wondering......what are the two open pipes going to or for?

Nevermind.....they are going to the intake correct? I didn't see the split pipes coming off the cooler at first

Mike could you explain why?? I have heard this but never had anyone that would explain it to me. Do you mean as far as spool up? or air speed? What does it affect? Ok I thought they were four. My bad!

loss of velocity has been proven over many years. i know banks did it on their 6.0 kit, and well, everybody that goes back to 3" find spoolup and power better.

The same volume of air moving threw a 3" pipe will have a higher velocity vs moving threw a 4" pipe is what I guess he means, thats how I would guess it would work at least. Should make more boost in the smaller area vs having to fill such a large area.

Edit: Big P beat me to it
