High Performance Straight Cut Air Operated Switchable Transom Mount Silencer Kit
At last, the ultimate silencer system receives the flexibility to go from a non-obstructed open water roar system to a marina quietmuffled system Thanks to the engineering and design of the Delta Style core and massive sound expansion chamber, no other switch-able transom mount silencer system can flow the large volumes of exhaust gas in a closed/muffled position as the Hardin Marine Cyclone But that is only the beginning These units offer the very longest in reliability due to the use of a pneumatic (air-activated) control panel that responds, activate, and holds better than imitation units that have retro-fitted farm equipment choke solenoids which are prone to intense heat, temperamental activation, and poor reliability Cyclone units conceal the silencer portion of the unit inside the transom and only protrude 6-inches inside the transom, allowing them to be used with any OEM or high performance wet exhaust system. No cutting or modifications are required like other brands. The entire silencer systems, as well as the included transom sealing rings, are constructed from 316L highly polished stainless steel, not 304 agriculture specifications. Just another Cyclone exclusive that you have come to expect from Hardin Marine products. The units are available in either a standard straight cut or angle/slash cut version with models for up to 475 horsepower and a version up through 600 horsepower and above. If you look closely at the picture you will see the "Expanded" section of the tip. This is known as the expansion chamber. When the flap closes the exhaust is diverted through a large louvered section of the expansion chamber and this is how the unit is muffled. This system DOES NOT use any connection to the factory y-pipe. When only the best is good enough for you and your boat, demand Hardin Marine! Uses 4" Marine Grade Soft Wall Exhaust Hose.
