Q:  Something is dripping from the muffler, do I have a leak?

A:  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.

Q:  How long does a muffler typically last?

A:  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.

Q:  Will a good muffler improve my gas mileage?

A:  No, but a restriction in the exhaust system will reduce MPGs and/or performance to the point that your car may not even start.

Q:  Can I remove my car muffler? What will happen?

A:  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. 

Q:  What is the difference between a muffler and the exhaust?

A:  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.

Q:  How do I know if it is time for a new muffler?

A:  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.
