Bisson makes some custom mufflers too. Not too sure about pipes. I would not wreck the Jett pipe if you have something else for it. Mecoa may have the plugs. He took over the K&B stuff. Not sure if the EVO has the middle reach plugs or the longs. I think it may be the middle reach, like most of the newer oriental stuff which would be OS or Enya. You would have to take the head off and look for the bottom of the plug being flush.
