nor-quiet underwater exhaust
 

what issues have people had with this system on 36 supercat, my boat has 800 teauge engines, carb, looking for best way to quiet it down, any idle issues, stalling, power loss? anyone have one of these set ups for sale?

it is a great system and you will be happy you switched it. Mine works great, nice a quiet around the docks. I don't believe there are any issue with the system but obviously Nor-Tech is the best to consult you......Instead of buying the system, just buy my boat.......all done :)

I didn't go the Nor-Tech route and used some 6" GGB units and quieted it down a ton...
