Hi got me a 2010 zx6r in standard trim. Was going to race it as have dun racing before, was wondering on results that can be achieved with a power commander, and / pipe? Ive purchased a slip on already, but was wondering if its worth the next step and by a de-cat connector pipe, which illuminates the huge back box, looking in the down pipe while box is off i see the cat is in the downpipes not this back box. Cost of commander, dyno etc aint cheap and if im gaining 2-5 BHP i can get that by visiting the loo before i go out but if gains are huge may be worth a go... Also any views on air filter? And a race suspension set up using the standard suspension (yes i know wer all different but a rough guide for a 80Kilo guy!).. Thanks boys!!! :):D
