For the record, I like a nice rumble as much as anyone, but unmuffled straight exhaust is unacceptably loud.

I bought my Donzi 26ZX used, but the boat came from the factory with Corsa Mufflers and the Quick and Quiet system. If you set the Quick and Quiet to the open position, 100% of the exhaust exits thru the mufflers. In this position my boat will have no problem passing the noise test. If you set the Quick & Quiet system to the closed position, approximately 80% of the exhaust is diverted thru the prop, the other 20% or so still exits via the mufflers. This quiets my boat down even more... obviously, it will pass the noise test in this position. I don't understand why switchable exhaust should be illegal if the boat passes the sound test either way? I really don't understand all of the opposition to it either...

Due to noise laws around the country most hi-performance boats sold nowadays are equipped with the switchable exhaust and mufflers too... I also know for a fact ole Merrill Faye sells his Chapparalls with switchable exhaust.... even though they are illegal in NH.

I don't think very many people will go thru the trouble of installing the switchable exhaust on an older boat... although with the current noise laws they will probably have to pony up the $$$ for a set of mufflers. The days of straight pipes are done! But those of us with newer boats that have a switchable exhaust can at least be mindful of our neighbors and be a little quieter... especially at night when people would be sleeping.
