Atlanta GM Dealer: Do You Have A Hole In Your Muffler

Your Atlanta GM dealer, the Southtowne General Motors Superstore knows that there’s something to be said for the roar of an engine and the loud rumble of a modified exhaust system. Muscle cars back in the day we’re renowned, not only for their power, but also how much noise they would produce. I guess this was an audible show of force.

But, if you know that you didn’t modify your exhaust system and your vehicle sounds like you did, then you may have a muffler problem.  It wasn’t too long ago that this very thing happened to a friend of mine. His car was quite loud!  Interestingly, some people purposefully put holes in their mufflers to achieve a louder car sound. I don’t recommend this at all as your muffle is a key part of your car’s exhaust system. Not only does it reduce noise, but it also prevents exhaust fumes from entering into the passenger compartment of a car. If exhaust is entering  your vehicle then you may be faced with even more problems than just a broken muffler. Fumes from the vehicle can be deadly.  If you suspect you have a broken muffler, here are some things to check out:

  1. Turn your car on and listen for low pitched rhythmic sounds or a rumbling. If you do have a broken muffler it will create a loud exhaust noise.
  2. Inspect your muffler for holes or rust. Rust usually happens from the inside out, and is an indicator that holes are developing.
  3. Look for unusual exhaust smoke. This may be a big cloud when you hit the gas or even a very subtle one.
  4. If you vehicle starts to slowly overheat, this may also be an indication of broken muffler. The exhaust system can affect engine performance.
  5. Check to see if there are any water leaks near the back of the car. This too is an indicator of a hole in the muffler.

If have done the above suggested checks on your vehicle but still are unsure, please schedule an appointment with the service department at the Southtwone General Motors Superstore to get this taken care of right away.
