Get the Right Muffler

The muffler on your vehicle affects how loud it is, how well it performs and how fuel efficient it can be. Some factors to consider when choosing a muffler are the type of exhaust system on your vehicle, the model of muffler you prefer and whether you'll be installing it yourself or leaving that to an expert. Here are a few tips to help you get the right muffler.

Steps

  1. Understand your options.
    • It's important to understand the different types of mufflers to find the right muffler for your vehicle. Mufflers are referred to as cancellation, absorption or diffusion models and are categorized according to the mechanism used to muffle the vehicle's exhaust and noise.
  2. Read your owner's manual.
  3. Choose a muffler based on the manufacturer's recommendation in your vehicle's owner's manual. The manual will help you understand what type of muffler will work best with the make, model and horsepower output of your vehicle and teach you what warning signs to watch for in case of muffler malfunctions.
  4. Consult your mechanic.
    • A mechanic with experience working on your type of vehicle can explain how certain mufflers will alter the sound and performance ability of your vehicle.
    • Your vehicle will require a single or double muffler depending on whether it has a single or dual exhaust. Consult your owner's manual or ask a mechanic if you're not sure which kind of exhaust system your vehicle is equipped with.
  5. Choose between a single and double muffler.
  6. Decide on performance or gas mileage.
    • Vehicle performance and speed is improved by increasing the exhaust flow through the muffler, which makes it louder and decreases fuel economy. Decide whether performance or gas mileage is more important to you.
    • Be sure the muffler you purchase has a warranty to protect you from malfunctions or damage. Some warranties include replacement trade-in options or discounts to make it less expensive to replace the muffler when it's old.
  7. Obtain a warranty.
  8. Enlist the help of an expert to install the muffler.
    • Choosing an expert to do the installation will cost more than doing it yourself, but will ensure that the muffler is properly installed and prevent any damage to your vehicle.
