    Comments about MagnaFlow Stainless Universal Performance Muffler, Oval Case Shape, Inlet Diameter - 2.5 in.:

    The Magnaflow mufflers were easy to install, light weight and have a mellow tone that is music to the ears. My wife and neighbors are thrilled I toned down the noise levels. Great product!
