Great video. Very scientific. Conclusion= shorty headers give you more torque above 5100 rpm and long tubes give more torque below 5100 rpm.
1 5/8" headers have peak torque at 4175 rpm
1 3/4" headers have peak torque at 4500 rpm (this one may be slightly off)
1 7/8 headers have peak torque at 5100 rpm
