FMF Megamax II or Powercore IV exhausts for 300EX
I am in the purchase for a new exhaust system and have narrowed my choices down to the Megamax II and the Powercore IV. If anyone has these pipes on their 300EX or any other Atv, I would appreciate it if you told me the quality of the muffler and the performance gains. Thanks.
