Emissions and Exhaust Systems
You may think your car’s exhaust system is designed only to reduce noise, but it is also responsible for reducing harmful emissions from entering the atmosphere.- Properly functioning mufflers and exhaust systems not only sound better, they are better – for you, your car, and the environment.

Your exhaust system really starts at the front of your car, right behind your engine. Exhaust manifolds connect to the cylinder heads, where they collect exhaust gases. As the gases move through the exhaust system,
they're first analyzed by oxygen sensors, then refined by the catalytic converter and, finally, muffled by the muffler.

So by the time those gases leave the vehicle, your emission system has made your car run smoother, cleaner, and quieter.

Any one of these components can fail and affect everything from your gas mileage to the air you breathe. It's a pretty complex system, but our emissions and muffler repair experts can diagnose the problem and get you right back on the road.

Mufflers & Exhaust Repair FAQs

Q: My car is older. ­Lately, it seems to be getting noisier.­ How do I know if I need muffler repair?

A: Your car’s exhaust system is pretty complex. Excess noise could be from a number of sources in the exhaust system including cracks or holes in manifolds, gaskets, pipes or the muffler itself. To find out for sure where the noise is coming from, just stop by your local Midas. Not only can we find the problem, we can fix it, too.

Q: How do mufflers actually work? Are mufflers made of special soundproof material?

A: Your exhaust system – and the muffler in particular – is very sophisticated, although you can’t really appreciate it just looking under your car. If you were to cut it open you would likely find what looks to be a bundle of metal tubes with holes in them. And while they might look simple, inside the muffler these tubes work together to force sound waves to hit one another in very precise ways, canceling the sound in the process. With all this hidden engineering, it’s no wonder mufflers can’t be a one-size-fits-all replacement part.

Q: Besides excess noise and rough idling, what are some other things I need to watch out for with my car’s exhaust system?

A: Excessive rust or broken rubber hangers can cause mufflers, pipes, and other parts of the exhaust system to hang extremely low or break, and that can be hazardous, especially to folks driving behind you. However, these aren’t always things that can be easily assessed by just peeking under your car. As a rule, we recommend having your exhaust system professionally inspected at least once a year.
