Holes that form because of corrosion or accidents are typically found on the part of the muffler nearest to the exhaust pipes. Below are some of the effects of having a hole in your muffler:<\/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\/2021\/06\/damaged-car-muffler-1024x709.jpg\" alt=\"damaged car muffler\" class=\"wp-image-39882\" width=\"1024\" height=\"709\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/damaged-car-muffler-1024x709.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/damaged-car-muffler-300x208.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/damaged-car-muffler-768x531.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/damaged-car-muffler-150x104.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/damaged-car-muffler.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Holes that form because of corrosion or accidents are typically found on the part of the muffler nearest to the exhaust pipes.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Excessive Noise<\/h3>\n\n\n\n<p>An unusual, loud, rumbling noise is the most noticeable sign that there&rsquo;s a hole your muffler. The muffler&rsquo;s primary purpose is to muffle or dampen the sounds coming from the engine. If the muffler is damaged, its effectiveness at keeping engine sounds to a minimum goes down drastically. As the muffler continues to degrade and the hole(s) get bigger, the noises may get even louder.<\/p>\n\n\n\n<p>While it is possible for there to be leaks somewhere else along the exhaust system, in many cases, loud exhaust is usually caused by a damaged muffler.<\/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<h3 class=\"wp-block-heading\">Exhaust Gases Entering Your Cabin<\/h3>\n\n\n\n<p>This is the most dangerous effect of having a hole in your muffler. Holes along the exhaust system can cause harmful gases to seep into your passenger cabin. These gases include carbon monoxide. Carbon monoxide is a deadly, odorless, and colorless gas that&rsquo;s produced by the incomplete burning of fuels.<\/p>\n\n\n\n<p>If you&rsquo;ve been exposed to high concentrations of it for an extended period of time, this gas can cause headaches, fatigue, nausea, dizziness, difficulty breathing, confusion, and even death.. Carbon monoxide is especially dangerous to small children and the elderly.<\/p>\n\n\n\n<p>Because it&rsquo;s odorless and colorless, you won&rsquo;t know right away if you&rsquo;ve been exposed to it until you start experiencing the symptoms. If you suspect that you&rsquo;ve been exposed to carbon monoxide, roll down your windows immediately to let fresh air circulate through the cabin. Have your vehicle checked by a certified mechanic as soon as possible.<\/p>\n\n\n\n<p>That being said, older vehicles or poorly maintained newer ones are more prone to produce CO (carbon monoxide) than vehicles built after the mid-80s mainly due to tightening emissions standards. Modern vehicles only produce CO2 and water, both of which are totally harmless. You might even notice how green the grass is right next to the road because CO2 from vehicle exhaust accelerates plant growth.<\/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\/2021\/06\/car-pollution-1024x727.jpg\" alt=\"car pollution\" class=\"wp-image-39883\" width=\"1024\" height=\"727\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/car-pollution-1024x727.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/car-pollution-300x213.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/car-pollution-768x545.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/car-pollution-150x107.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/06\/car-pollution.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>A hole in your muffler can allow emissions to freely enter the atmosphere and harm the environment.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Pollution<\/h3>\n\n\n\n<p>Aside from the uncomfortably loud noise and potentially lethal gases, a hole in your muffler can allow other emissions to freely enter the atmosphere and harm the environment. A hole in your exhaust can also make you <a href=\"https:\/\/www.carparts.com\/blog\/how-to-pass-an-emissions-test\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fail emissions tests\">fail emissions tests<\/a>.<\/p>\n\n\n\n<p>Of course, the muffler and\/or resonator is typically after the catalytic converter(s), which means that any gas leaking from a hole in your muffler is no worse than the gasses coming out of the <a href=\"https:\/\/www.carparts.com\/tail-pipe\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"tailpipe\">tailpipe<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Weep Holes<\/h3>\n\n\n\n<p>Mufflers are in a very hostile environment and have a difficult job, especially in road salt states where the whole underbody of the car becomes a study in rust formation. But water can gather in the muffler if there&rsquo;s no way for it to drain.<\/p>\n\n\n\n<p>Thus, many mufflers have a small hole located toward its rear called a <em>weep hole<\/em>, and it&rsquo;s there for a very good reason.<\/p>\n\n\n\n<p>But first, a bit of a chemistry refresher. Water is a byproduct of burning fuel. For each gallon of gasoline burned, approximately one gallon of water (in the form of steam\/water vapor) is produced. The water vapor then condenses (or turns into liquid) on the cooler areas of the exhaust system (particularly in the muffler) until the vehicle is driven long enough to push the temperatures in the exhaust system past the boiling point of water (212&deg;F\/100&deg;C).<\/p>\n\n\n\n<p>Because water accumulates in the muffler, it needs to drain out somewhere to avoid corroding and damaging the rest of the exhaust system. This is why your muffler has a weep hole.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Drive with a Hole in Your Muffler?<\/h2>\n\n\n\n<p>If you suspect that there&rsquo;s a hole in your muffler or anywhere else in your exhaust system, you should immediately have it checked by a certified mechanic. Driving with a damaged muffler can put you and your loved ones at risk, so don&rsquo;t take any chances.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get a Replacement Muffler Delivered to Your Doorstep<\/h2>\n\n\n\n<p>Replace a holey muffler as early as you can before it causes problems. Otherwise, your vehicle will fail its next emissions test, or have other issues like strange noises caused by the exhaust gases escaping through the holes in the muffler&rsquo;s walls.
