PLEASE PLEASE PLEASE!!!! Search this forum right here. A while back, Calvin and I touched on this very subject. There is so much more than just the size. The step lengths,the angle of the tube off the top of the radius of the exhaust port, the radius of the tubes you use, the overall lengths, collector size and length. Merge angle and degree make a huge difference on these as well.

Do some homework, it will pay off better than you can imagine. To get the most out of this combination, dont use an old design....totally proven...
