Just picked these up today. Can't wait to have them installed. Looks like the mechanic will have to weld a flange to the flex pipe for this to work.
First impressions is that they're not as heavy as I though they would be. The finish is quite good, the welds look good and the insides of the flanges and pipes are smooth.
Here are some picks
Getting them installed tomorrow. I'll take more photos after the install and give driving impressions.

I got them from an online store (www.onautos.com.au) , but picked it up from the shop/office to save on shipping cost. They're in Australia (Melbourne). The headers are made in Sydney (Australia).
They look nice, but hopefully they go nice too. Took it into my mechanic today, he had a look under the car and look at the headers and said to bring it in Monday. I was hoping he would do it today! There is a Mega Honda cruise in Melbourne on Saturday, would have been nice to have them in there (for showing off).

Yeah, this particular exhaust isn't on the site, but you can email the dude sales@onautos.com.au and enquire about Hurricane exhaust headers for the 3rd Gen prelude. Give him your engine code as well.
I don't know if he ships overseas though. But, its not much cheaper than DC Sports if you consider the possible shipping fees. Especially with the Aussie dollar at the 0.80USD mark.

oooo... i need to get a set of those... i kept the header the same on my b20 so my midpipe doesnt line up with the rest of my exhaust.. this would fix that problem while getting rid of my header rattle which is even in the jdm version
i emailed the guy about getting one, he said that they are 270AUS$ which isnt bad, but the shipping to the US is whats going to be the killer. until i find something decent im going to get a Pacesetter or some **** brand for my JDM B20A, but by time i have that installed ill probably have another option
Originally posted by racinghonda The o2 sensors are there because they're designed for the B20A6 (144hp) & B20A7 (150hp). I'd imagine that you would have to plug them with a bolt?
yeah, whats the price on getting one of those over here to the states?
Whoaw! The headers have been fitted. There were some issues with stuff not lining up, but my mechanic did a great job in the end. The flanges had to be rejiged to fit properly.
Driving impressions? 1st thing I nocticed was no extra sound. 2nd thing was that the car pull more smoothly in lower revs and there is definetely slightly better torque down low and a nice increase midrange. At around 4500rpm there is a increase in torque. But the big surprise is at 5500-6400rpm, in 1st and 2nd there is a nice shove in the back. In 1st the rev needle whips through to the red line! I wasn't ready the 1st time and had to hurry my shift to 2nd. And in 2nd it pulls hard.
So all in all I love them. Best performance mod I have done so far (air filter was the other). Butt dyno says 7-8kw (10hp) at least and maybe 10-15nM of torque increase.
Here are some pics of the installed headers. They are so much bigger than the stock ones.
I want to point out that these headers are definetely not a DIY solution. Maybe I got unlucky but, it does require some exprience with welding and pipe heating/bending.
To start with, the header downpipe was touching the engine cradle that runs along the car, so the mechanic had to heat up the pipe and mandrel bend them to the left slightly. Then he had to make a 1cm extension for the flex pipe as the down pipe wasn't long enough. He also had to change the angle of the flange (where is connects to the flex pipe) so that it kinks up and left to clear the sub frame and for a bit of extra ground clearance.
I have to be carefull not to bottom out on the new headers now. They are pretty low, but they look phat! All up, I have spent $515AUD ($415), for all the parts and fitting. So assuming I got 10hp it was $41 per HP. Pretty good considering that the K & N cost me about $80 and I am lucky to get 1hp. Bang for buck is pretty good I guess.
