Got SBP pipe in the mail. I am looking for a header pipe length (from very start of flange until first point of expansion) to give strong top end but also decent low end. I have a pretty modified, high compression motor if that makes a difference.
start long and slowly shorten little by little undtil your happy. or substitute your header pipe for a peice of flame resistant hose and once again start long and shorten. once you find your ideal length, make adjustment to your pipe.
