I have two sets of Teague Switchable Mufflers. All have been tested and work perfectly, also in very good condition visually. 4" inlet 4.5 exit. $1000.00 for both sets.

How do these work? Do I need a y-pipe to make the exhaust go through the prop, just like factory switchable?

No need for a Y pipe. It diverts the water and exhaust through a internal muffler when you close the exhaust then strait out when open. They quiet the boat a very little bit when open but a LOT when closed. I have them on my Formula and found them to be very nice. You do loose some power when they are closed. I open them up if I am going over 3500RPM's

Are they air actuated or eletric

They're Electric- I'm not 100% sure I want to sell these yet. I need to get my engines in the boat and see how loud they are. If you're really interested in them you have first dibs on them.

As I would like second dibs, need something behind the new Stellings!

Thanks

Sell them to tax free..I am in the thought process of selling my boat for a new one right now..since the old lady found a boat that is bigger...

Still Available if anyone is interested! These are in very good condition.
