I still say that if you take my car and put 2 1/4" crush bent piping on it from the catback and hayame muffler, the numbers would be identical to the same setup but w/mandrel bent piping. No increase or decrease.

Fluids(liquids, gases) flow quickest when it is laminar meaning no turbulence. Everything flows nice and smooth. Think of laminar flow as straight parallel likes and turbulence flow as random squiggles(sorry bout the spelling and the terminology:fawk: that flow around, in the turbulence flow, the air gets "in its own way". Most is moving forward while some tries to oppose itself as it swirls.
Simply, laminar = more air out quicker = more power:thumbup:
cause it's tight!

I used to have one made by Focuz that wasn't. It was one of those ones where about a foot of the pipe is 5" while the rest is the normal size. It was welded where the pipe changed size. Has anyone seen these? They DO make a difference in sound; it was a loot deeper and throatier than the CAI I have now, but the power gain was about the same.
Overall, I just thought it was fugly and looks much nicer in my brother in law's 1989 RiceTegra

even in this case, id be willing to bet the gains(if any that are due to the type of bends in the piping) would be so minimal it wouldn't be noticed unless u were out on the drag strip counting tenths and hundredths of seconds while running forced induction too. Anyone have any idea how much it would cost to get a dyno run? I would like to run my car w/existing setup and then again after dc header and catback.
