Python has created a look made for Harley-Davidson touring bikes! The Python Black Rayzer 2-into-1 Exhaust System is touring-bike ready with 1-3/4" head pipes under the protection of a sleek, black heat shield. With both 12mm and 18mm O2 sensor ports, this exhaust system can work with a variety of aftermarket fuel management systems. You'll love the look and sound of the radically designed turnout megaphone muffler that's a full 4" at the outlet.
