Hi ben
Am running full system pc5 and k&n filter.2010 gsxr1000.
Sometimes stock filter works best, had mine dyno'd by brad at bikebiz he probably can work with woolich.
My concern was not hp priority more keeping bike from running lean/hot.
Although most yoshi slip on's are 3/4 cat delete with no need for tuning.

Thanks mate. Yeah I'm not worried about horsepower. Just don't want to destroy the engine.
