Thanks Mark, Guys,

Street headers usually have varying tube lengths, some may be more than 2" difference how bad does that hurt the HP. Equal length competition headers may be 1/8th of an inch or wider diameter than usually used for that application, say 2 1/8 vs 1 7/8. How much effect would that have on HP?
