Re: BISIMOTO Engineering header for D series are coming soon. (Bryant)
Whats the old saying:
"Imitation is the sincerest form of flattery"
But then I really don't know squat.. just pulling ya crank
Cool looking headers Exo...one question, it states drag header..
so that would imply a street driven vehicle would see no benefit?
Please correct me if im wrong.
( Hey at least you were smart enough to post a pic )

Re: BISIMOTO Engineering header for D series are coming soon. (Bryant)
probley not, kinda looks like someone took the idea from AN-R.com
Theres alot that people dont know who arent in the circle of these fabricators. Little do you know that these people all know each other, are local of each other, and sell each other's parts in some cases. I dont believe that AN-R makes the parts they sell... but then agian I may be wrong. I do know that there is 1 guy that made all these headers popular and are being used by many southern cali racers.

Re: BISIMOTO Engineering header for D series are coming soon. (exospeedAMcrx)
For those of you who don't know who Bisimoto is, head over to http://dseries.org and search through some of his posts.... Some of the things this guy comes up with to drive his N/A SOHC D15 CRX into the 10's baffles the mind. the man knows his stuff!!! This Header is a 4-1 design with equal length, stepped primaries and no ground clearance issues like you have with other 4-1 headers. The final product should be ceramic coated and he plans on making a street version that bolts to the factory exhaust. If he keeps the price anywhere near where he wants to sell them at, these headers will be a steal for the amount of design and fabrication that goes into them!!!

Re: BISIMOTO Engineering header for D series are coming soon. (FourthGenHatch)
The price Bisi wanted to keep this around was a good deal but I'm not gonna drop any numbers 'cause it hasn't been announced yet but good to finally see a header w/some thought put into it for the D

Here's a few quotes from Bisi himself that will hopefully answer some questions out there:

The powerband designed for is of the narrow 5000-8300 range. The venturi has proven to do some nice, but weird gains at below 4000.
The venturi at the collector is of 2.25" diameter and the outlet pipe id 2.5"
Header coating is recommended since the design is of mild steel, for longevity and heat retention.
The radius bends are very wide coming off of the head to prevent velocity loss, and negate power losses as a result. All of the d series headers on the market have steep bends out of the head, and hence hurt velocity and scavenging. To allow clearance, collector placement and for asthetics, the wide bends continue accordingly.
The piping has a 1 5/8" primary that steps to a 1 3/4" with a true merge collector. the collector alone, purchased on the market, will rival the cost of this whole Bisimoto header system.

That sounds like a good idea to me, just can't wait to see the results and price. Hope it will be available summer time. Lates!

Bisi said dyno testing should be done soon on these headers to see if there are any adjustment need to be made to get the maximum HP out of this header.

Its a Bisimoto Design. for the D series. Bisi himself is designing this header and doing the actual R&D for the perfect design.
Theres alot that people dont know who arent in the circle of these fabricators. Little do you know that these people all know each other, are local of each other, and sell each other's parts in some cases. I dont believe that AN-R makes the parts they sell... but then agian I may be wrong. I do know that there is 1 guy that made all these headers popular and are being used by many southern cali racers.

update dyno numbers in...
bisi has posted the dyno numbers pretty imporessive considering the price.. the street version will be $569 and the race version (side exit) will be $599 that is what was posted on another board and a direct quote from bisi by e-mail. check them out the baddest header on the market for a d series period!
