      FMF Powercore 4
      by Mike S. on 06/14/12
      Pros: the pipe sounds great, and it opened up the top end of my motor.
      Cons: There are stretch marks all over the aluminum where it looks like they had to force the end cap into the pipe. Some of my friends said this is not like FMF. Over all its a good pipe though.
