I have an fmf powercore 4 and its great it sounds awesome. You will probably need to rejet but that is relatively easy to do with basic tools and skills. You do not need and aftermarket air filter.

Although you would see better gains with an aftermarket air filter in combination with the pipe and jetting.

FMF says a 150 or 152 main jet for a stock airbox and filter with the snorkel removed and stock pilot with 2 turns out on the airscrew.
