I´m going to replace my stock header on my B18C1:engine...
But there is a whole world of different headers on the market..

Which one gives the most value for the money?

 

The dc jdm 4-1 is nice and fairly cheap. Inlinefour.com has them.

 

You should be able to find an OEM JDM 4-1 pretty easily, and they're pretty decent.

 

RPMmotoring was gonna do a GB on DC headers, but word has it their customer service sux

 

So I should forget S&S??

They look alright from the pictures, but honestly I've never heard of them.

 

Has anyone heard about them?

 

There's a good article on Honda-life, comparing headers. Different headers will work better for you with different mods. I wouldn't stick a HyTech long primary on a car with no other mods. Likewise, I'd be hesitant to stick something cheap (no names :P ) on a car with lots of mods.

I was originally looking at getting a Type 1 Racing header for mine (with minor boltons, but more to follow) but they're hard to come by. The one distributor for North America was out last time I checked. I'm going with a JDM ITR 4-1 with 2.5" collector instead. They offer similar numbers (although a lot rougher band) and cost a couple hundred less.

 

So if I understand correctly...
Your going to put a stock ITR header on your C1?

 

The stock JDM header on my JDM C1, yup. The only mounting difference between a C1 and a C5 as it relates to the header is the length of the collector and subsequent position of the cat.
