The Cobra Classic pays homage to the 1960s’ chopper-style exhaust, but is updated for the 21st century with modern construction and materials. It sounds way better than stock, but not as loud as our shotguns. The muffler bodies swell up to 2.5 inches, giving a nice finish to the head pipes. These are going to be a great pick for riders who appreciate their rich sound and timeless good looks.
