New for 2015, this 4-inch slip-on system gives you the sound and look you would expect from a premium muffler. At an incredibly low price. The 4-inch diameter, 909-Twins feature a unique scalloped and smooth rolled outer tip that is matched with a scalloped inner tip. This "Twin" tip design gives an elegant look. Especially because there are no visible outer screws securing the core. We use a 2.25-inch louvered core for its traditional and recognizable Harley sound.
