This episode has everything you need to know about the exhaust muffler, or in British English, the silencer. We cover what it does, why it's needed, and then chop a muffler up and see what's inside. I also talk about exhaust back pressure and the differences between turbo muffler, absorption or straight-through mufflers, and finally we look at chambered designs.
