Cool Magnaflow muffler. All mufflers are not created equal. Those who choose to place aftermarket mufflers on their vehicles know this fact to be true. We seek out mufflers that keep our cars quiet, in an attempt to not produce noise pollution or to not hear the roar of our own engines. But car enthusiasts, racers, junkies, modifiers, ricers...whatever you want to call them, are a different breed all together.
