Those old Campbell silencers, whilst quieter than standard silencers, were very restrictive and reduced performance considerably. Although I have never taken one apart I believe the inner tube had a smaller internal diameter and that there were more spirals than the original silencers.Is anyone familiar with Campbell straight through mufflers for the Vincent? They are advertised as being N.O.S..
