that video is useless because in no way shape form or fashion can you compare the motor to our motor. yes everybody says 1 3/4 are better for our trucks and I also have 1 7/8 but in a 8 speed 3.92 you spend way more time in the upper rpm range with that combo than with other combos hints the more time your in that range the more power you make for a longer amount of time which makes you go faster or at least the same for less cost. what I'm getting at is I bet there isn't enough difference in the two hp wise and the cost difference is pretty substantial but if your running say a 6 speed with 3.21 then I'd say 1 3/4 but an 8 speed any gear I'd say both would be fine and I'd bet the 1 7/8 would be a little better up top oh and also Matt has said before that 8 speed 3.92 is a whole different animal and 1 7/8 will do just fine. obx is half the costDyno runs don't lie, watch the video, even Moe's said on here quite a few times 1 3/4 are best for our trucks.
I have 1 7/8 cauz JBA's are the cheapest headers that are bolt on. If I had the cash I would of gotten 1 3/4's
Lucky for me i'm not trying to make a brick into a sports car, So the cheap headers with a little less down range torque were ok for me.
