That's why I said GOOD CAI, good being the key word. Though pipe length, to an extent isn't really gonna affect you at all. There is only so much pipe you can put in a contour/cougar. What does affect you is pipe size, bends/turns, and pipe type. Darrel's was mandrel bent, 3" with smooth bends and good placement of the filter. So it gave really good gains. If you have access to a dyno and can mandrel bend some pipes, then you have the makings for a good CAI.
