      great exhaust
      by Nicholas L. on 03/19/13
      Pros: easy in/out spark arestor. Has snug Fit with power bmb header. Has a really smooth sound, its deep and loud but not too much.
      Cons: crated a lil more back pressure then my old exhaust so has some back fire.
      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.
