Based on our success with our 4-2-1 H22A headers...I am up to making some 4-2-1 D series headers for you guys. They will start out with small primaries up top 1 5/8" tapper bored into 1 7/8" ID downpipe runners then into either your choice of 2 1/4" collector or 2.5" collector. Our header will perform over any of the lower brand headers and will be a bang for it's buck. It will come with Cerma/Krome that is a high temp. coating. It comes out white chalky then take some fine steel wool to it and few swipes it comes out shiney within seconds. It also does a very good job keeping header temps. down. There is no discolor upon fireup. My Crx header looks the same the day I put it on a 1+ years ago. The header will be designed for stock to NA builds and for 88-00 D series SOHC and SOHC Vtec engines. Our server is down so the below link will show you to pictures for the time being. -John

$410 shipped US...If I can get 5+ people interested I will drop the price down to $375 price just for this time being...

WHere are you located and will you do dyno testing, because if you can prove that it will make power than i'd be in.

Im not volunteering but you should try it on a built car and a basically stock car. I know builthatch has a sick build but uses smsp. A guy named eyal 951 uses a dc header so you could prove yours is better in that way. Then you should try someone more basic. Just my .02
410 shipped is a damn good deal too. Good luck.
