The muffler is the most obvious component of your vehicle’s exhaust system. The purpose of the muffler is to quiet the sound of the exhaust. Without a muffler, your vehicle would make an atrocious noise and would be practically undrivable on the street. You always want to install a quality muffler on your vehicle, such as an Apexi muffler. An Apexi muffler, like all mufflers, works on the same principles as a pistol silencer. It functions by reflecting the acoustic waves around the barrel of the muffler. The waves cancel each other out, quieting the exhaust. Of course, for this system to work, is has to reflect the waves around, which takes power. The Apexi muffler is designed with performance in mind, which means that the Apexi engineers worked to make the muffler as non-restrictive as possible. The result is a performance-oriented muffler that quiets the exhaust without sacrificing power. The Apexi muffler is not as quiet as an OEM muffler, which is not necessarily a bad thing. So replace your rusty, worn out muffler with a quality Apexi muffler. You engine will sound great, and you will actually gain some power over an OEM system.
