Re: tell me what u think of my NEW EQUAL LENGTH RACE HEADER (97jrscgsr)
There's more to a header than being equal length. The best path for exhaust is the simplest one. Any disruption of exhaust flow, including bends, takes away power. With all of the extra piping used to make it equal length, you probably lost real-world power with all of the extra weight. 
There is also more to it than just the gases themselves. You also have to take into consideration pressure waves, which with that much bending, are probably really screwed up and run into each other in the collector in a bad way. I won't even get into the secondary waves being screwed up.
On the other hand, it looks cool
Best way to design a header - Pretend you and someone else are on two seperate slides that merge at the end. You go down a second before the other person. You should end up at the bottom of the slide exactly one second before the other person being as bored as possible.

What was the total horsepower w/ the jdm 4-1 versus yours. I'd just like to know what the percentage of horsepower gained is. That makes a difference to me at least

with the JDM 4-1 header on my supercharged GSR i made 219 at the wheel and when i install this race header i made 231 at the wheel

A JDM type R header hinders performance on a SUpercharged motor anyway. Superchargers like short primaries. That header(the twstied one) was not designed with a supercharger in mind either. You could probably spend less time and money with a Kamakazie header and make more power than either header mentioned above.

too bad the kamikaze leaks like a bastard....

it looks like there are the same type, and amount of bends that the header has so i don't see how it will be clogged up in the collector please explain?
with the wieght it's probbaly only like 2lbs, nothing to complain about.
Also very nice header
looks like my AN-R

Im not a super header expert or manufacturer, but I don't totally agree with the comment aout "best path is the simplest one" I have been told by a few old school race engine builders/engineers that this is not necesarily true. In GENERAL it does work, but for maximum torque , that air should travel evenly throughout the piping and that the shorter distances on certain part of the bends will cause turbulence in the flow. if you look at a bending pipe, air can travel faster on one side of the pipe and take longer on the outer side. so to prevent uneven ness i guess, the bends help keep the uneveness all throughout the piping and thus creates more torque.
This is from what I was told. chime in on comments if you want.
in comparison, the Bisimoto header put out 8hp over a stock manifold on a stock D16Z6. Do you think a regular 4-1 DC header will push out that much?

Where did you get these control arms? How much lighter are they then stock. Do they have front sway bar mounting points? How much? where?? they look decent!

Yea, don't mean to hijack your header post, but where did you get those?

Those are the Competition Engineering control arms and a link in case your interested http://www.competitionengineer...21002
