Just wanted to know if anybody on here uses one of these headers for their RRRR. If so i wanted ur opinion b/c they definately look different than ur "everyday" aftermarket header. Thanks.

Bump... I have been looking in to this header as well.

 

Haven't seen anyone use it yet...you buy it and report back y0!!

 

never heard of it and would only trust it with detailed pictures of the welds and whatnot. you should buy it like mikehonda said and post pictures and a writeup.

 

i believe member:Sinbro2 has it on his itr..

sexy header

 

My freind put one on her GSR and it looked great, but no before and after dynos. The welds look good, just not sure of the design

josh why do these look like anr headers?

 

Personally I like the design....

although they dont look bad, i have to agree that they look somewhat like the anr header. i wanted an anr header before i found out that you cant have A/C. that doesnt fly in Florida during most of the year.

 

haha looks cool, let me know as well.

yes ur right..with A/C good bye....same problem with AN-R..
i want them..damn A/C

 

that header looks sexy!!!

 

yeah those dudes are right down the street from me! the welder is amazing, you should see some prototype work he has done. never seen dynos charts on them, even at the shop. ill talk to them soon if you guys would like?
let me know

 

How does something like this flow efficiently??

*scratches and tilts his head from left to right*
good question

 

just a guess...

maybe because of its length, it smoothes out the exhaust pulses and allows for better flow....

once again just a guess...

They are called Equal length headers:

"Mostly found in a full length header design, the equal length header has equal length primary tubes. They have been shown to make more power in an open header race car, but no measurable gains have been found when used with an exhaust system. They also work in a much narrower rpm range than unequal length headers and are more expensive. The highest gains shown with this type of header was with engines with 180 degree crankshafts, that make each bank of a V8 have even firing. The usual crank configuration leaves 1 out of sequence cylinder on each bank.

The above link btw is nicely informative about header tech and may be worth a look if you are interested.

 

It looks like an AnR copy and he makes a damn good header.....

 

This looks like a quality piece. Notice the gradual flare of the pipe after the collector, and the sudden flare at the b'pipe connection.


Also, note the flare after the collector in this design.


Some attention to detail went into these. Be nice to see some dyno's.

And there's the rub.

As others have hinted, the advantage of an equal length header pretty much disappears when you have to add the exhaust piping for street use, converters and resonators.

I'd love to see a dyno of one of these on a street car with a decent exhaust, but my instincts tell me that someone who spends the money on one of these is going to be disappointed if it goes on his street car or hybrid track/street car.

 

I'm informed that I should be cautious with the use of the phrase "equal length" because we are apparently throwing the words around unwisely. Apparently the OEM headers like the OEM JDM 4-1 header are also "equal length"--but the header shown in this thread is clearly an extreme example.

Clearly, an "equal length" header designed by Honda engineers is designed to be used with an exhaust system.

 

Those sure do look pretty. But I really wonder how they perform. I think more imformative than looking pretty and equal length would to get primary length & size. Also those don't appear to be stepped at all. But most important (to me at least) would be to get a good shot of the collector as that IMO is the most critical in getting good flow (assuming you're not a moron and can build the rest of the header)
