What is inside the muffler?

Inside a muffler, you'll typically find a series of chambers and perforated tubes designed to reduce noise from the engine's exhaust gases. These components work together to dissipate sound waves and lower the overall noise level by allowing gases to expand and cool as they pass through. Some mufflers also use sound-absorbing materials to further diminish noise. The specific design can vary, influencing the muffler's performance and sound output.
