dc headers? what year?

[1.5]

^ exactly. Being shorty headers, I don't know how much of a difference the design would make in whp. I know on my DC which is a 4-1 design, the power gain and sound comes around the 4-5k range.

I used to have a k20 Si coupe and on those apps, a race header added like 10+whp alone and I can attest to the 9k rpm redline, especially if they were running kpro or the hondata ecu reflash. Man I miss those revs.
