Exhaust Systems & Muffler Repair

Dunan Muffler Repair - Exhaust SystemsWhile your vehicle’s exhaust system is, in part, designed to reduce engine noise. It also reduces harmful exhaust gas emissions. A healthy exhaust system and muffler not only sound better, they are better – for your car, for you, and for the environment.

Your exhaust system starts at the front of your car, where your exhaust manifolds connect to the cylinder heads, and there collect exhaust gases produced by the engine. As these 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. Therefore, by the time the exhaust gases leave your 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 breath. All in all it’s a pretty complex system, however our emissions and muffler repair experts can diagnose the problem and get you right back behind the wheel.

Duncan Muffler Repair & Exhaust Systems Frequently Asked Questions

What is that smoke that comes from my exhaust pipe?
Normally, this is nothing to worry about, unless you see smoke coming from the exhaust after the engine is at operating temperature.
Something is dripping from my muffler. Is this dangerous?
Not to worry. What you’re seeing is water condensation draining through the muffler’s drain hole or out of the end of the tailpipe. It’s completely normal and caused by the engine itself.
How long does a muffler typically last?
Since the 1990’s, most exhaust systems are built with stainless steel, and modern engine management systems are controlled by computers. These advancements allow the muffler to last for years, and in some cases, depending on where you live, a muffler can last the lifetime of the vehicle.
Will a good muffler improve my gas mileage?
No, but a restriction in the exhaust system will reduce MPGs and/or performance to the point that your car may not even start.
Can I remove my car muffler? What will happen?
It’s definitely not a good idea. For starters, you’ll no longer be able to use your cars on U.S. streets or highways, and it will also be unbelievably LOUD! Exhaust fumes will also enter the cabin of the vehicle, which can cause illness or even death. Yikes.
What is the difference between a muffler and the exhaust?
An exhaust is the entire system, from the engine cylinder head to the tail pipe. It includes the exhaust manifold, catalytic converter, muffler and all pipes and hardware that connect it to the chassis.
How do I know if it is time for a new muffler?
If you hear noise that gets louder when you accelerate, you may need a new muffler. Keep in mind that noise is only an indicator of an exhaust system problem. We’ll detect the exact problem at your local Midas store.
