lol. mine is carbon on my zx10 and on my 1098.
the big issue i had w/ my akra is there is the tube inside the can, when u cut it even, it cuts even. to get the cap back on, u have to cut it lower, it was a PITA.
i plan on getting rid of the Leo's for full "new" termi's eventually. so i guess if i screw up a bit it wont hurt.
