Description 




APL designs incorporate a flow through center which helps exhaust products to pass with minimal restriction. APL technology reduces noise levels while retaining that special sound that says power. All APL marine mufflers are made from 316L stainless steel for long life in the marine environment. The In-line silencer was first offered in 2003. It does an excellent job of quieting harsh noises produced by marine engines. It is used on exhaust systems with through hull tips.

Installation is straight forward: remove a section of rubber hose between the riser and tip then use four hose clamps to secure the silencer.

Note: Power Ratings assume dual exhaust gasoline engines. Ratings are reduced by half when all engine exhaust flow passes through a single muffler. Ratings are also reduced by half when mufflers are used on diesel engines. In-Line designs require a wet exhaust system.
