There are several important active components on your exhaust system. The most obvious part of the exhaust is the muffler. It sticks out of the back of the car, so it is really the only visible part of the system. It is also the part that has the most obvious effect. The muffler is designed to quiet your engine's exhaust, and without it, your vehicle would make an unbelievable racket. The Ansa center muffler, like all mufflers, works like the silencer on the end of a gun barrel. It redirects the acoustic waves around the muffler and they cancel each other out, significantly quieting the exhaust. The Ansa center muffler has an eye on performance and economy. Ansa has long been regarded as a manufacturer of excellent replacements that are less expensive than OEM parts, perform better, and last longer. The Ansa center muffler, in many cases, may even work with some of your OEM exhaust systems, although you should always check on this before ordering and installation. The Ansa center muffler is designed with smoothly polished welds, giving it a fantastic appearance in addition to its great performance.
