How a Muffler Works

Подробнее о видео

Here's a look inside a few car mufflers and how they work!

The purpose of a car muffler is to reduce the amplitude of exhaust sound coming out of the tail pipe. With different designs, the exhaust note can be changed to suite the application.

There's three types of mufflers, chambered, turbo and straight through style. In this video, we cut open a pair of Subaru turbo mufflers (one OEM and one aftermarket), a Toyota turbo muffler and a straight through glass pack muffler. Inside the turbo muffler, baffles and perforated pipes allow sound waves to bounce around and cancel each other out through destructive interference. Inside the glass pack muffler, fiberglass padding converts sound waves to heat, absorbing sound by reducing its amplitude.

This is also a comparison between the dual muffler system on the Subaru Outback, with one being aftermarket and the other being OEM.
