GMC SLE Exhaust Muffler

About

An exhaust muffler is a device that connects to the exhaust pipe of an internal combustion engine that reduces its exhaust noise. It is designed with a resonating chamber that causes destructive interference. As the exhaust gases pass to the exhaust muffler, the opposite sound waves cancel each other out, which in turn results in a reduced noise output. A damaged exhaust muffler will produce annoying noise when the engine is running. Auto Parts Network hosts a wide variety of parts that will improve the performance of you vehicle. Hide
