Best inframe exhaust for a 10mm cub

[drap660]

I believe its 465cc. Is that to much for the current CPI(small bore) inframes I have. I think CPi says its cut of is 440cc. Just wondering if I can get away with it? If not whats the best(most power) inframe exhaust system I can get? I saw the CPI(big bore's) but am just wondering if there is anything better. all I do is drag on asphault. I hit a trail once in a blue, then right back out to the street.
