Cobra 4" 909 Slip-On Mufflers4
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.
The chrome have a life-time warranty, but the black only has a 90 day warranty.
Incredible styling, great sound, lifetime warranty and a $399.95 price. Tough to beat.
