Q: My car is older, so it seems to make more noise. How do I know when mufflers go bad? - Zack
A: Dear Zack,
Your car’s exhaust system is pretty complex. Excess noise could be from cracks or holes in manifolds or gaskets. Or on your muffler itself, excessive rust on a muffler, or holes in a muffler can cause a louder ride. Bad mufflers may also lead to increased pollution and even a rough idle. If you’re not sure, stop by. At Tire Pros of Frederick auto repair advice is always FREE!
