Full Size X-over kit
stumbled across this while looking at auto tune kits on the fuel moto site. will it really make a diff? i know on trucks and cars it is always a good thing to get retrictions out of exhaust. wondering if it is worth the $119 to upgrade.

maybe if you are flowing alot...high rpms.
most of the exhaust flows out the right side...it's a straight line.
when the right side can flow no more, then the left side comes into play...the gasses have to make 2 90ş turns
not something i need for my stage 1 96"

I think the main benefit would be more equal sound.
When I ordered mine, it was made clear that without the XXX 2-1-2 and a big horsepower the full size X-over won't make any difference.

With most of the mild builds that are on the street, I dont think it will make much if any difference other than reducing ground clearance. On most of the 2-1-2 set ups the reason they work well is the back pressure produced and the fact that more of the exhaust is pushed out 1 side.
