TCM ST-450 Switchable Exhaust Mufflers

Teague Custom Marine ST-450 switchable exhaust mufflers give you the best of both worlds: wide open performance and sound, as well as comfortable and legal cruising noise levels. Operated by a switch at the dash, these mufflers feature a solenoid that opens and closes an internal butterfly valve to divert exhaust gasses through an outer jacket. No unsightly and bulky Y-Pipes or pneumatic pump setups required; these are the ultimate marine muffler solution. Now USCG approved and Mercury factory certified for warrantied catalyzed Mercruiser engines!
