The most common problems include:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Leaks\">Leaks<\/h3>\n\n\n\n<p>Over time, the various components found within the exhaust system can develop leaks. An exhaust system leak is a serious problem because it can expose you to deadly carbon monoxide. Furthermore, a leaking exhaust system can cause the oxygen sensors to interpret a false lean condition, potentially leading to engine performance problems and an illuminated check engine light.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Obstruction\">Obstruction<\/h3>\n\n\n\n<p>Parts of the exhaust system can become obstructed due to impact damage or upstream engine problems. When the <a href=\"https:\/\/www.carparts.com\/blog\/how-to-tell-if-the-catalytic-converter-is-clogged\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"system becomes clogged\">system becomes clogged<\/a>, it creates excessive back pressure, effectively choking the engine. As a result, the vehicle may exhibit problems, such as lack of acceleration, hard starting, and an illuminated check engine light.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"Loose_Components\">Loose Components<\/h3>\n\n\n\n<p>The heat shields in an exhaust system can become loose due to impact damage or missing fasteners. When this happens, you&rsquo;ll likely hear a metallic rattling noise coming from the undercarriage.<\/p>\n\n\n\n<p>Also, the exhaust hangers can become worn, allowing the exhaust system components to move around and cause clunking or banging noises.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Where_To_Buy_Parts_For_Your_Exhaust_System\">Where To Buy Parts For Your Exhaust System<\/h2>\n\n\n\n<p>There&rsquo;s no doubt that the exhaust system is essential to your vehicle, and keeping all its parts in tip-top shape is essential for smooth, clean driving. If you find any leaks, obstructions, or loose components among its parts, it might be time for a change. The last thing you want is for these issues to affect your vehicle&rsquo;s emissions.
