Got the pic?
Its really a matter of opinion on who's header is better. If Kami tuned theres for low end like RPW did than you could make a better comparision. But both companies make quality products just one is great for top-end (The Kami) one is great for low-end (The RPW). Its up to you!
the Kami is like $275-330
the RPW is like $600 (Roughly)
You'd also want to get a AFC relatively soon after to utilize the headers full potential and squeeze that last 5-7hp out of the headers.
