A muffler remains an integral part of any car’s exhaust system. It works by dampening the noise coming from the engine through the inlet pipe before releasing the resulting sound through an outlet pipe.
By doing this, mufflers reduce noise pollution by suppressing the sound coming from your car to make it more tolerable. Apart from noise dampening, mufflers play an essential role in regulating the backpressure of the engine to optimize its performance and efficiency.
That said, how do they actually work their magic? Are they anything more than chambers and tubes enclosed in a steel body? What model exactly should you buy for your vehicle?
Well, our coverage provides answers to these questions. It also suggests some of the 11 best mufflers we have out there. Let’s set the ball rolling to see the perfect purchase for your car!
