RGO is a small shop in japan. i stumbled on them. check this B header

discuss.

i had the description translated.

To be the tend pipe collapsing was lost in vendor processing with the hand bend construction method. In addition, the swirl each inside of pipe can be obtained effectively the gathering section by making the pyramid top which is close to ideal form. Because of this it can obtain power and the torque which balance are taken. Road clearance was guaranteed the gathering section by carrying to the front from the oil pan.

 

reminds me of rmf, some how

 

i just like how there isnt a from the flange to the collector. it would not surprise me if those pipes were bent using the old sand method.

thats how donF built his when he used to out run the police in the 30's during prohibition when he smuggled moonshine.

im going to have my GF call and ask what the diameters are. if they are on par with what the 2 liter stuff normally i might see about getting one.

 

I like the one piece primaries and the maad jdm heat coloring.

 

not too fond of the collector or the length of the tail section afterwards.

for a street car it would prolly be decent

 

the primaries look wayyy to short. looks like its designed to make peak torque at like 10k... something similar with longer primaries would definitely make more power.

 

X2, the throttle and the collector diameter are too small for most set-ups.

Maybe, this would work on a mild 1.6L.

 

fwiw - Rmf made a few h2b headers that only had 2.25 inch collectors and still worked very well . . . If the header is designed to work on a motor with a certain power band, i'm sure the collector size that is on it , has something to do with it

 

whats the price tag on that thing in japan like 500,000 yen lol

 

LOL....

This header kinda gives a resemblance to bamboo with its smooth gradual bends.

 

It looks like the "sand method" from the pics.. Just like Mugen use to do when they made their headers.. Nice piece.

 

i actually think they look too long for making good peak power.

also a stepped design would work better imo to provide a smoother transition from port to collector. unless that is a way small collector inlet.

overall i would say the primary and tail pipe lengths are both too long and the collector looks too short/abrupt.

 

That header is for B16. The American aftermarket requires a more HP potential.

 

What confused my though is that its featured both on for civic's and integra's on there webpage, so I'd assume it was offered in both 1.6 & 1.8L versions.

 

I just saw this header on the bay area craigslist not to long ago.The owner only wanted like 550 for it. He stated his version was titanium and it came complete with the catback exhaust and header.

 

that header is for the tall deck B16B. in USD with todays exchange rate it is 1170 bucks. give it a week though, our markets improving, itll be a grand.

that couldnt be Ti could it? or could it?

my guess is on a B16B with mild cams it would probably be awesome but it would probably choke a 2 liter B, since 99% of japan doesnt know or care what a B20V is other than a motor that wont pass JCI inspection.
