    can I get a deeper sound out of my 08 YZ450F?

    the performance is and will always be the goal, i was just wondering if i could get a deeper sound if i added an insert..
  3. Ok guys, I have always bees a street guy so forgive the noobish question.. I picked up a used 08 yz450f with a fmf4.1, megabomb header already installed. Is it possible to get a deeper sound from the bike? I hear some of these 450s and they are very deep, throaty rumbles.. Mine sounds like a 250 on roids! Thanks for looking! D
