Description 




Our clamp-on silencers quiet harsh noises produced by high horsepower marine engines very well. The most exciting feature is that no power is lost in most installations which makes it an ideal marine racing muffler. The Clamp-on silencer is a compact and light weight version of our product. High power models are frequently used on 1200 horsepower supercharged engines.

Exhaust systems using through transom tailpipes that dump all the water into the exhaust stream at the very end of the pipe, such as Stellings and CMI, typically have noise reductions that are 3 db greater than the ratings shown.

Installation is straight forward: slide it onto the pipe and clamp it in place. All models accept an external rubber flaps for additional surge protection.
