      by Joshua W. on 02/07/15
      Pros: -Absolutely perfect sound (more on the dirt bike side of the sound scale)
      -Heads now turn as I ride past rather than not hearing me
      -super easy installation (stock was harder to take off)
      -only took me (someone with no experience at all) 2 hours to install going very very causiously and slowly.
      -Came very well packaged (To Australia)
      -Express shipping was SUPER! fast
      -The price is incredible!
      -Looks amazing on the bike
      Cons: -Because this is the american model it does not have the hole for the Co2 emission plug but a bit of welding and it'll be sorted

      (It's worth it for the savings on the price

      No other cons
