I have searched all over and I can't seam to find a dyno comparison between the jdm itr 4-1 header and the dc jdm 4-1 header with 2.5 collector.

I can get the dc a little cheaper but that is irrelevant, I'm looking for dyno charts comparing the two on the same car.

If anyone can help I would really appreciate it.

 

hay go to clubsi na fourm and do a search it was done buy hx_guy i think about 2 weeks ago.

 

thanks for the tip.
