ding ding! I believe even fuel/direct injection engines need some kind of back pressure along the line

Well if you get smaller diameter than you don't need longer collectors. The bigger the diameter of the pipes, longer collectors you need ideally to grab low end torque. Hence the design differences.

Thats why my collectors are so long as opposed to BBK's, now apparently bigger diameter pipes carry torque better on the high RPMs. Or I am talking straight out of my ass

Large tubes are generally better at high RPM. For a drag car, that's fine. For my purposes, midrange torque should help more.

Jannety slapped three different sized headers from ARH to see how much difference in HP and TQ they made throughout the RPM range on the same SS in one day.
The largest dia. tube had the largest HP and TQ gain throughout the entire RPM range.

That was an interesting test. Prior to that test, most small block chevy's show the opposite is true.

I wonder how much of that holds true for the V6 engine. I didn't go the biggest pipes I could find, but the 1 3/4s make a huge difference, I only wish I could get on the dyno. My shop's been ridiculously busy.
