What do you guys reckon are the best headers to use on a H23A?
I assume it's the Mugen gear, but they really cost the earth... is the expense worth it?!

 

For a H23A Mugen doesn't produce a header for that motor. If I had a 4th gen I'd get a Greedy.

 

GReddy doesn't make a header for the H23A either.

And it's headeR, not headeRS. You only have one.

 

Probably DC Sports. Or go with any other company like Airmass. You really don't have a lot of choices. The stock h23a manifold sucks, so anything aftermarket should make more power.

 

How is the stock h22a4 header on a 5th gen? Any way to modify it so it has a 2.5 in. collector? I heard of several people doing this to a DC Sports header.

 

Thanks for the info guys. ATM I have a dodgy Hurricane header on it, but I have had to head and bend it about 4 times to stop the flange plate rubbing against the water pump. As a result I don't think air flow is much improved, cause the first bend is so sharp now.

 

I'm not too familar with the 4th gen but isn't the H23A motor the Si motor for 4th gen and doesn't this link http://www.greddy.com/products/headers_frame.htm show that Greddy makes a HEADER not HEADERS for a 4th gen motor.

 

In OZ, we call the 4th Gen H23 (thats 2.3L NON-VTEC) Si
the NON-VTEC 2.2L (think it's an F22) is called S
and the VTEC 2.2L is the H22

So no, that link does not show headers for my car...

Thanks anyway though!
