Hi,I am in the middle of a total rebuild of my boat and before I get started on putting the motor back in I noticed that the exhaust shutters in the y pipes are totally gone on both sides,question is should they be replaced or leave them off?i have seen arguments for both but trust the members on this site know what they they are talking about,so I figured I would ask here.thank you!!!
