i also heard a lot of different things about headers. some guys said that they are worthless, no gains. some other guys say that they will give you 5-10 hp but only in higher rpm range, losing some low end. anyway, i thought someone once posted hp gains for various types of headers, but i can't find it anymore. maybe it was at probetalk.com anybody remember that old post?
