I bought an 11HP Craftsman pressure washer. The engine is a Briggs and Stratton, Intek model. This is an awesome pressure washer. But, it sounds like a dragster (ok I'm exaggerating). I called Briggs tech support and they said they were working on a solution, but it may take 2 years. I will lose a lot of hearing in 2 years, and my neighbors may set my house on fire when I go on vacation (I'm still exaggerating).
I was thinking of running it in my garage with the doors closed and running extra hose. This would probably work, but the risk of Carbon Monoxide poisoning is too great to try it I guess.
So, does anyone know of a solution to this, aside from buying an electric model? I don't want to part with this machine. :(

Only way to quiet the exhaust is to fabricate a larger and thicker muffler or buy one that is larger that you can modify to fit the original bolt pattern and exhaust port size. I've done it on a few customers lawn equipment and with a skilled tech in welding is not that difficult although somewhat involved in layout and design. If the original muffler for the unit has a piece of pipe coming off it for exhaust, you could try attaching another muffler to it for say a small motorcycle or minibike of the same diameter pipe. Surprised the Briggs people would take that long to come up with a solution.
Another simpler solution is to build an insulated open-top box of plywood and foam insulation board to surround the washer with and direct the sound upwards---open top is necessary as it needs air flow to operate the engine or run it in a shed or garage if possible to deaden the noise. You'd have to ventilate the garage somehow or hook up a heat resistant hose to the exhaust and duct it outside with a blower like auto garages do.

I dont suggest using it in the garage. Whenever i use any motorized yard equipment- i use earplugs/earmuffs.
Id suggest this - its similar to the other suggestion. If it has threads into the engine block, where the muffler is - get some black pipe - enough to go straight out from the motor to clear everything, then 90 degree it straight up, probably about 3-4 feet ( too long a pipe and itll restrict the motor). Id go the size out from the motor and then increase the size a bit , so itll breathe better. It should decrease some noise for you. If it doesnt have threads into the block, some sorta adapter can be made to attach it to the motor.
