oh trust me bro, they know the bike......it's been reported more than once I'm sure, but really though, they won't let me take it up there and let her rip....I'd love to, but I ain't holdin my breath

Everyone dyno graph that I have seen with comparison of C30 vs. C21 shows that C30 is just a little too big for the 70cc kits, maybe someone should blow this exhaust trough with a TCR/2Fast and see what differences there are from C21 to C30, and then try the TCR exhaust and the XSH 2F4R exhaust.

For minarelli it has only 26mm (diameter) for both

They are 99% the same, header is the same dimention but made in parts...
Noticeable diference is the last cone that is a bit twisted but dimentions may vary in a few milimeters
