gutting the cat and air box mod??

hi, just wondering if i was to gut the cat and do the airbox mod and put hi flow filter in, would i need a power commander or will it cope on its own? also got a mivv suono can on.
thanks :Rockon:
 
If you don't want the expense of the power commander I'd skip the airbox mod. Should be fine with the slipon, cat gut and filter but it surely would be better off with a PC and a proper tune.
