How to Maintain Your Car’s Exhaust System for Longevity

The exhaust system is a big part of a vehicle’s performance – but many people don’t even think about it until there’s a problem. Just like changing the engine oil and checking the tires, regular system maintenance will lead to better exhaust performance and help it last longer. In this guide, we look at how to check the exhaust system and four things you can do to stay ahead of potential issues.

1. Self-inspection and What to Look for

You should check the exhaust system a minimum of once a year. Problems will often present themselves visually before they start affecting performance, so this is a good way to catch them early. Here’s what to look for when inspecting an exhaust:

• Rust and corrosion – they weaken the components and eventually cause performance issues.
• Other damage such as holes, cracks, dents and loose parts.
• Incorrectly aligned pipes.
• Broken clamp connections.
• Burned gaskets and seals.

Pay particular attention to the flex pipes and the parts furthest from the engine as these are most prone to failure.

2. Clean the Exhaust System

After looking the system over, you should give it a good cleaning, as the build-up of dirt, grease, grime and carbon deposits will affect exhaust flow and heat levels. A mix of mild soap and water will be sufficient for the exterior. To get the deposits on the inside, use a specially formulated exhaust pipe cleaner. Avoid abrasive cleaners as they can mar the finish and remove any protective layer.

3. Address Leaks

If your exhaust is leaking, it’s not just a performance issue – it poses serious health risks to drivers and passengers. Always be on the lookout for potential leaks, which can present themselves as hissing/popping/rumbling sounds, foul smells, lower fuel economy and a loss of power. If the leak is due to a failed gasket or seal, these can be replaced without affecting the rest of the system. While you can use high-heat tape or an epoxy bond to temporarily plug holes in an emergency, you should still replace the part as soon as possible.

4. Buy Replacement Parts

You don’t necessarily need to replace the entire exhaust system if there’s a problem. Oftentimes, you can swap out individual exhaust tubes, mufflers, flanges and other parts. This will be less expensive and time-consuming than a full system replacement. Regardless, faulty parts should be replaced immediately to prevent small problems from snowballing. Be sure to get high-quality parts so you don’t end up back in the same boat in a year or two. Also, check compatibility before ordering to make sure the parts are the correct size.

Expected Lifespan of an Exhaust System

How long should an exhaust system last? In most cases, you can expect an OEM system to last for 5-7 years. Factors like weather conditions, road conditions, inferior parts and constantly driving short distances can speed up the deterioration process. Conversely, regular exhaust maintenance and premium parts such as those from MRT will extend the system’s lifespan while saving you time and money.
