Overview Reviews Similar Products –> Product Description When that big storm starts brewing, you can rest easy knowing that, thanks to the muffler, your standby generator will quietly start within seconds of power failure. Also known as the silencer, the muffler reduces engine exhaust noise to slow down and cancel the sound waves caused by combustion. The Generac 0K7780 Muffler guarantees a quieter generator runtime. Mufflers rely on a process called destructive interference. With multiple internal chambers, baffles, and tubes, the muffler is able to create opposing sound waves that cancel each other out. When the exhaust gas passes through, it bounces off the added surfaces, slowing down and reducing pressure before it is forced out the tailpipe. When you buy an OEM Generac part, you are investing in the future reliability of your generator. The right Generac muffler can make a world of difference in how your engine runs.
