Hey, I'm going JRSC in 2 years, so this summer I was looking at getting a DC Sports header dropped in. Seeing as how I'm not going All-Motor, I didn't look at the header as a CRITICAL part of the horsepower-generating machine, especially in comparison to the SC and all. But I need some opinions here. I know SMSP and Mugen are the best, but running a JRSC on these, will it really make a difference in the big picture? And if you think so, what do you think the whp difference is going to be?
