hey, just wondering what sort of performance improvements i will get with a set of extractors, my zook already has a 2inch system from the muffler back, but exhaust manifold and i think catalytic converter are stock.

cheers

Slight.

Its gonna be a seat of the pants gain rather than a measurable number. But fitting extractors and a new cat AS WELL AS getting the carby tuned to suit will give you a few more horses.
