Generator Muffler Buying Guide

There are many things to consider when buying a muffler for your generator. You’ll want to make sure that you’re investing in a high quality muffler that’s going to be effective at mitigating noise without wearing down quickly. Here’s what to consider when searching for a super quiet generator muffler.  

Generators Noise Levels

The most important thing to consider when purchasing a muffler is the noise level. Your muffler should keep your generator quiet enough that you can easily have a conversation, and it won’t be distracting when you are trying to work on other things. 

The best generator mufflers can reduce noise levels by 10 to 15 decibels or even more. Some generators, especially those made by Honda, are the ones that won’t need any generator mufflers as they are already quiet enough. We’ve rounded up some quiet running generators that you should check out, if you still haven’t made your purchase. 

Generator Muffler Silencer Kit

A full silencer kit comes with everything you need to keep your generator quiet. They come with mufflers, which attaches to the motor to minimize the sound coming from the exhaust pipes, which are the loudest part of the generator. 

A silencing kit may also come with tools to help you deflect the sound away from you by pushing it in a different direction, as well as everything you need to maintain the muffler and keep it in good condition. 

Muffler Materials

It’s important to make sure that your muffler is built to last. The best mufflers are made from durable materials that won’t rust or break down with extended use. 

Stainless steel and aluminum are both very effective materials for generators, because they both are resistant to rust and corrosion, and they won’t lose their shape over time. A well-built muffler will resist heat, cold, and precipitation to maintain its function over time. 

Pricing Range

Of course, the price of the generator is also an important thing to consider when shopping. The best mufflers will require some investment, but shouldn’t cost more than the initial price of the generator itself. Assess your budget before you go shopping to make sure you don’t overspend on a generator muffler.

Our Verdict

A good muffler is an absolute essential for anyone with a generator. While many generators come with a muffler, they typically aren’t very effective and can wear down easily.

Buying a new, high-quality muffler is the best way to minimize the sound coming from your generator. We’ve assessed the mufflers in this guide to ensure they are long-lasting investments.
