How Do I Know My Exhaust System is Working Properly?

Here at Placentia Super Service, we have customers all the time asking about why their fuel efficiency might be lower and their emissions might be higher. Most of the time, this has something to do with their exhaust system. 


Your car's exhaust system is a vital part of its performance, and it's crucial to ensure it's in good condition. If your exhaust system isn't functioning correctly, it can lead to significant problems. But how do you know if your exhaust system is working correctly? Here are five tips to help you know when it's time to get your exhaust system checked out.

1. Check Your Vehicle's Emissions

One of the easiest ways to tell if your exhaust system is working properly is to check its emissions. Excessive emissions can indicate something is wrong with your exhaust system, so it's crucial to inspect it if you notice an increase in emissions.


Here in California, emissions tests are required every so often, and if your vehicle doesn’t pass this may be a sign that your exhaust system requires some inspection. Even if you do pass and your emissions are a little higher, I’d highly recommend getting an inspection!

2. Monitor Your Fuel Efficiency

If your car is having trouble maintaining its fuel efficiency, it could indicate something is wrong with your exhaust system. A faulty exhaust system can reduce the efficiency of your engine, making your gas costs appear to be higher for the same amount of gas you always get. 


This is why it’s so important to keep in mind how much it usually costs to fill your tank. Sure, gas prices fluctuate, but if you’re noticing a fuel efficiency issue over an extended period of time it could be your exhaust system!

3. Listen for Unusual Noises

When something goes wrong with your exhaust system, one of the most common signs is increased noise. If you notice a loud, rattling sound or an exhaust smell in your car's cabin, something is likely amiss with your exhaust system. If you hear any unusual noises, it's vital to get your exhaust system checked out.

4. Examine the Exhaust Pipe and Muffler

You can also check the condition of your exhaust pipe and muffler to get an idea of how your exhaust system is performing. Look for signs of rust, holes, cracks, or other damage that may indicate a need for repair. If you notice any issues, addressing them as soon as possible is important to prevent further damage.
