The best way to quiet your cruiser without interfering with the performance is to use K&B’s In-Tube Silencers. The installation only takes a few minutes so you will be back in the water in no time enjoying your cruise.





With our In-Tubes you don't need to take out or replace your old fiberglass water-lift muffling system. It is designed to run in conjunction with the current system and it slips into the rubber exhaust hose between the manifold and exhaust port making this an inexpensive and quick solution for any muffling problem.
