Part of it has to do with the <a href=\"https:\/\/www.carparts.com\/blog\/exhaust-system-parts-101-the-basics-diagram-included\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"exhaust system\">exhaust system<\/a>, specifically the muffler and resonator. These exhaust parts both alter the exhaust note produced by the <a href=\"https:\/\/www.carparts.com\/exhaust-system\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"exhaust system\">exhaust system<\/a> in different ways. Let&rsquo;s take a closer look at mufflers and resonators and compare the two parts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Muffler?<\/h2>\n\n\n\n<p>A <a href=\"https:\/\/www.carparts.com\/muffler\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"muffler\">muffler<\/a> is a metal device that reduces the noise emitted by a vehicle&rsquo;s exhaust. This part contains multiple chambers with perforated tubes and baffles through which exhaust gasses pass. The perforated tubes reduce the volume of the gas as it expands, forcing it to exit the muffler through an indirect route. The result is a muffled exhaust note. A <a href=\"https:\/\/www.carparts.com\/blog\/what-are-the-best-mufflers\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"muffler\">muffler<\/a>&rsquo;s design determines the exhaust volume. Stock mufflers produce a softer exhaust note because of their restrictive design. Muffler upgrades can change the exhaust note and reduce back pressure.<\/p>\n\n\n\n<p>Some mufflers are made with materials such as fiberglass to deaden the exhaust noise. Mufflers are frequently paired with resonators because they can&rsquo;t target specific frequencies within the exhaust system.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler-1024x683.jpg\" alt=\"muffler\" class=\"wp-image-70537\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/muffler.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>A muffler is a metal device that reduces the noise emitted by a vehicle&rsquo;s exhaust.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Resonator?<\/h2>\n\n\n\n<p><strong>A muffler only reduces exhaust volume but has no effect on pitch. A <a href=\"https:\/\/www.carparts.com\/resonator\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"resonator\">resonator<\/a> tunes the exhaust noise to eliminate the high-pitched sounds heard inside the vehicle while the engine is running at a high <a href=\"https:\/\/www.carparts.com\/blog\/what-does-car-rpm-stand-for\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"revolution per minute (RPM)\">revolution per minute (RPM)<\/a><\/strong>. Sound waves of a particular frequency bounce off the inside of a resonator to create a smoother exhaust note.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the Difference Between a Muffler and a Resonator?<\/h2>\n\n\n\n<p><strong>Mufflers reduce exhaust volume while resonators change the sound of the exhaust<\/strong>. They complement one another to create a pleasant sound that isn&rsquo;t too loud or unbearable for drivers.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Do You Need a Muffler and a Resonator?<\/h2>\n\n\n\n<p>Most US states have federal laws requiring motor vehicles to have mufflers. For example, in Minnesota, you can get pulled over if your vehicle&rsquo;s exhaust produces a sharp popping or cracking sound. Meanwhile, in Colorado, you&rsquo;re prohibited from modifying the exhaust system to amplify the exhaust noise.<\/p>\n\n\n\n<p>Despite the legal risks, some enthusiasts choose to remove their mufflers to get a louder exhaust note. This process is called a <a href=\"https:\/\/www.carparts.com\/blog\/is-a-muffler-delete-illegal\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"muffler delete\">muffler delete<\/a>, and it involves bolting an exhaust pipe in place of the muffler using a kit. Removing the muffler can improve exhaust flow and reduce a vehicle&rsquo;s weight. But it can also increase the risk of rust in the exhaust system if it isn&rsquo;t done correctly. You can also remove the resonator from the exhaust system to get a more aggressive exhaust note. A resonator delete won&rsquo;t increase the exhaust volume, but it can lead to a <a href=\"https:\/\/www.carparts.com\/blog\/how-to-pass-an-emissions-test\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"failed annual emissions\">failed annual emissions<\/a> inspection. Make sure to do your homework before modifying your vehicle&rsquo;s exhaust system to avoid problems.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator-1024x681.jpg\" alt=\"automotive resonator\" class=\"wp-image-70538\" width=\"1024\" height=\"681\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator-1024x681.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator-768x511.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/07\/automotive-resonator.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>A resonator tunes the exhaust noise to eliminate the high-pitched sounds heard inside the vehicle while the engine is running at a high revolution per minute (RPM).<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">When to Replace a Muffler and a Resonator<\/h2>\n\n\n\n<p>Mufflers are designed to last the life of the vehicle, but they can <a href=\"https:\/\/www.carparts.com\/blog\/what-are-the-signs-or-symptoms-of-a-clogged-muffler\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"wear out\">wear out<\/a> faster when exposed to road salt and moisture.
