"Sound-Selection" Air Activated 4" Exhaust Diverter System - "Captain's Call" Replacement
Single Engine Standard Exit System For Small & Big Block Chevy

At last you can have the very best of both worlds. You can go from marina quiet thru-prop exhaust to the open water roar of thru-transom exhaust. With no cutting or modifications, these highly polished stainless steel exhaust diverters install simply to both stock and aftermarket exhaust systems. But that's only the half of it. What makes the Hardin Marine Sound-Select Diverter America's No.1 choice is it is air activated - yes air activated - the same way the factory original guy's do it. You ask why air? Reliability and safety. Reliability because we DO NOT retro-fit electrical solenoids as marine exhaust components. Electric solenoids produce a continuous draw of electricity while generating possible sparks and heat in an enclosed engine compartment. An air operated system is driven by a remote mount panel providing none of the side effects electrically operated systems have. So if only the best will do for your boat do it the way the factory intended to do it - Choose the Hardin Marine Sound-Select Exhaust Diverter!

Each Sound-Select Diverter system is constructed of aerospace stainless components. The systems are sold complete with 2 diverters, and 1 remote operation panel. Exhaust tips sold separately.

These kits are designed to be fitted in stock bravo exhaust locations. See this measurement sheet for more info. If you must place tips in a different location more hose and angle bends may be required. Call us if you need any assistance. Note: This is for Mercruiser Bravo Applications Only! Will not fit Volvo/OMC applications.

These diverters will fit Bravo and Alpha applications 1987 and up they will not fit the 8.1 engines, OMC or Volvos.

The Mercury 350 dry joint exhaust will not work with the Hardin diverter.
Corsa has a set part number 270-61000 for standard non riser spacers. If there is space, we need to know if it is 3" or 6" and Corsa can build a custom set.
