A Tale of Two Mufflers
Muffler technology has changed significantly since the days of the muscle cars of the 1960s and 70s. The distinctive sound of these iconic cars was produced by straight-through designed mufflers using early absorptive technology. Now, reactive muffler technology makes the world a quieter place.
The early absorptive type mufflers use a packing material that causes the sound to interact and convert it to heat by means of friction. Reactive mufflers use a series of chambers and plates to reflect and direct the sound, causing it to cancel out in the process. Both absorptive and reflective type mufflers are still available on the market. Some are available on the market that use both reactive and absorptive methods for noise cancellation.
