Does anyone have some dyno results with the two headers? Is the DC copy any good?

 

the DC should be about $100 cheaper. DC has a true 2.5" collector, JDM ITR has a 2.375" collector

 

Im pretty sure they both have a true 2.5" collector. Someone back me up here?

 

The DC JDM has a 2-1/2" OD/2-3/8" ID collector. The JDM ITR has a 65mm (2-9/16" OD) and a 2-3/16" ID collector. The ID on the ITR JDM is smaller due to the anti reversion chamber in the collector.

 

So...what does everybody prefer, DC or JDM..

 

where can I find a DC sports copy of the JDM ITR header
does anybody know?

 

a lot of people here have used the JDM 4-1 and removed the reversion chamber...so they would still be similar in size after that.

 

From what I saw on the DC site, it isn't a copy of the Honda JDM header. It's an aftermarket part for the JDM R. They are now selling it here. I would guess the DC would be better if it's supposed to be an aftermarket part in Japan. Anyone else know anything different?

 

I looks more like a copy of the MUGEN header, I think.
