4-2-1 makes more midrange power at the sacrifice of peak hp and 4-1 makes more peak power at the sacrifice of midrange power.

that is all bullshit. it all depends on the collectors, piping, etc.

actually the distribution of the horsepower depends mainly on the primary tubes' and secondary tubes' length and diameter. "primary and secondary tubes" meaning the header design(ie 4-1 or tri-y/4-2-1) the collector's design does affect the end hp result, BUT the header tube design affects WHERE in the powerband the actual power goes.

how about before you raise the bullshit flag you do your research and state your facts to your claim. dont just say" bullshit...etc" tell me why you think i am wrong.
