Tips

  • If you are not experienced in repairing automobiles or don’t know how your vehicle is built, do not install the muffler by yourself. You may break the exhaust pipe. Hire a professional to install the unit for you. 
  • If you want to install it by yourself, jack up your car or place it on a level lift table for easier access. Apply an exhaust sealant on the muffler’s inlet pipe before fixing it in place for an airtight fit. 
  • Consider using a hacksaw and a penetrative lubricant to remove the original, worn-out muffler. Take care not to damage the other parts as you cut through the muffler.
  • To test the efficiency of the muffler, run your engine for about 30 minutes to determine how the unit sounds. If you notice a rattling sound or leaks accompanied by smoke and steam, then you may have installed it incorrectly.

FAQs

Q: Is a glass muffler noisy? 

A: The primary function of a glass muffler is to contain the sounds produced by your engine. It dissipates the sound waves to create a more bearable sound from your engine. If you get a high-quality muffler, it can amplify the deep sounds to make your engine sound powerful as opposed to being noisy.

Q: How long do glasspack mufflers last?

A: It’s a bit difficult to slap a lifespan number on a glasspack muffler, since even the most high-end versions can break down if mishandled or exposed to rough driving conditions. The more the muffler is exposed to water vapor and dirt, the quieter and less efficient it becomes over time.
