2point6 those header(s) are sick, equal length is the only way to go on an NA motor. I also have never heard of RMF but I have heard of SMSP and AN-R headers which are a simalar to RMF's design.

For the haters on this thread that think DC header are the shit, if you are to lazy to do some research on the web then check out any of the import mags that do header test. Tell me why DC always seems to be at the bottom of the HP and TQ gains vs other headers?
