How to Reduce Muffler Noise
- 1). Check that you have the correct muffler for your car model. Often, used cars have the wrong muffler because the previous owner desired a louder vehicle. By simply changing the muffler for one that corresponds to your car, you can greatly reduce muffler noise.
- 2). Look inside the muffler for significant deposits of debris, rust, soot, or other junk that might be contributing to noise. Make sure the engine is off. Check for visible holes, leaks, or loose pipes.
- 3). Check the muffler straps to make sure they are intact. Muffler straps, also known as exhaust hangers, hold your muffler in place and connect it to the bottom of the vehicle. Sometimes, these straps break due to normal wear and tear, causing the muffler to shake and rattle. Replace these straps if they are broken.
- 4). Turn your engine on and note the kind of noise your muffler is making. This will be valuable information for your mechanic. Common bad muffler sounds include hissing, booming, rattling, etc.
- 5). Take your car to a mechanic to have it inspected professionally. A good mechanic can advise you on what to do about the muffler noise. He or she may suggest replacing the muffler or other vehicle part and also be able to repair the muffler at a lower cost than total replacement.
