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.

Hey man. I have the same thing going on. If i were you i would go with the HMF exhaust (sport series) with the quiet core. yes, the FMF does sound better, but it fits all wrong. look it up on youtube. the pipe sticks out almost 2 inches farther than the rear grab bar. the megamax fits well, put i heard that you notice no power difference. The HMF has good reviews, just a little noisy. you can spend the extra 25 bucks to get the quiet core.

Hope this has helped,
