Topic says it all, any guys done it?

I wonder if there are some pics of these to see the difference...

Is it like old DC2 where JDMs were absolutely superlative in compare to crapy us/euro headers?

 

Well considering the ITR uses a 4-2-1 system versus 4 short primaries dumping into a large single pipe, yes it is alot better in all aspects. It is not great by any means though, it is quite heavy and the welds inside the primaries connecting to the flange are pretty crappy. The DC2 4-1 was very clean compared to the DC5 4-2-1.

 

I wonder what gains would only the header make on K20A2 engine.

If is it as succesful as previous JDM DC2 header....
