I was just thinking how is he gonna mock these up? Since you asked for oem headers does that mean he is doing it without a engine or car to use for measurements?

Would think you'd need a car to guarantee fitment and figure out best way to run pipes.

well if they don't have the car then they surely must have some sort of jig made up that they can base their measurements/clearance off.. if not then there is no way to line everything up.

Make sure its a cls-6 they're using for measurements. Otherwise they will be in for a surprise when the 6 speeders attempt the install.

That is why I've been pushing to make this happen. I want to maximize the potential even J30 Full bolt-ons keep up with me.

Everything's been taking care of. I needed the OEM manifolds/J-Pipe so that if people buy these sets, Most HFC's/Test-pipes will bolt up as well as the aftermarket exhaust system of their choice. I don't believe everyone is setting up for a custom exhaust so I wanted to keep that in mind.

Taking the right steps to go about this. I know how this forum is, I'd be chastised and burned at the stake if I didn't execute it properly.

I was just commenting on the mount thread that dragged on forever. And then resulted in a few us blowing said mounts in less then 10k miles.

I've been reading up on some custom long tube headers on the j32 forum. Some sweet setups. I have a question will these production long tubes eliminate the j bent and be a straighter design? I am looking forward to these and will be purchasing a set.

I assume you mean the j pipe? And they shouldnt, otherwise they'd be unequal length and performance would most likely suffer.

You mean like this, without the loop into the other? One could only hope. The civic guys really seem to like this setup

This is on a J series engine

Equal length primarily refers to the length of the runners being the same length until they merge into a collector or themselves

Right, but if the exhaust pulses where the collectors merge are out of phase, thats not going to help performance either.

I've been doing quite a bit of reading on this and its pretty split on whether or not they need to be. I've seen quite a few OEM exhausts that aren't the same in length, my expedition being one of them. I highly doubt there would be any bad effect or negative by doing so, especially with the gain in flow you would get. like I said before, the biggest thing would be that the runners are the same length before merging.

My brother said equal length headers essentially translates to power because of engine harmonics. Since it's a V-6 engine; every time it cycles it creates a burst of exhaust air. If the lengths don't support the engine harmony then the bursts could mash up and create flow issues which turns into a loss of power.

Search the internet. That statement pretty much gets voided due the fact of mufflers and back pressure (unless in turbo apps where exhaust temps will vary greatly with different lengths). What seems to be the most important is getting the right primary dia.

Exhaust headers with equal length tubes have been shown to develop slightly more power on an open exhaust system, but not when hooked up to a street system with mufflers. Fact is, most street motors with shorty headers will produce the same power as they would with expensive equal length headers.

Equal length tubes can produce more power, but they have to be the right length for the specific motor at the RPM range where you want the power. What that means is lots of custom fabrication and dyno testing, which translates into lots of time and money.

^^^ Well I'm not a hardcore tuner or engineer so I just decided to relay the basics of it that were explained to me. Thinking about that logically, it would still seem beneficial to have everything flowing in-sync within the pipes.

Here's a link to a Subaru WRX that uses EL and UEL headers.
EL:
The RPMs seemed to drop faster after he let off gas.
More droned sound
UEL:
Deeper rich sound
A lot more sound like an American muscle car.

The description also says he's catless so that probably reduces some of his restrictions.

I'm not trying to debate this, EL or UEL whichever offers better gains, I'm all for it and willing to buy!

^ You really can't compare EL/UEL Subie turbo headers with a setup for our car. With that said, its been proven time and time again that EL headers for Subies make more power.

Like I said above, its a little different with turbo applications where you want/need them to all be the same length to spool the turbo. Also with turbo cars the different lengths can cause much higher egt's which isn't good. The main thing with headers being equal seems to be that they are the same length to the collection (where the 3 cyls come together for each bank) after that the lengths can be different but will benefit from a x pipe or H pipe to equalize both banks.
