Hi i want to upgrade my 2004 Honda 300ex with a new exhaust and jet kit. i was wondering if i should get the Fmf powercore 4 or the Fmf megamax, or if you have any other suggestions that would fit the 300ex let me know. how much of a difference would i notice in the new muffler and would it be easy enough to install on my own or just better off sending it to a shop thanks

 

The power core 4 will give you more power but it will be louder then the mega max.

 

procircuit t-4,fmf blows,if u want a really mean pipe get the new white bros carbon fiber pro silencer n headers wit there jet kit u will think ur riden a yfz or 450 r well not quit but ull be somewhat close
