Description for Cobra 909 Twins Black Slip-On Mufflers

Want that classic Harley rumble without dropping months' worth of bike payments? The Cobra 4" 909 Twins Slip-On Mufflers feature a scalloped and smooth-rolled outer tip matched by a scalloped inner tip. That inner tip is part of the constant velocity, spiral-louvered cores that give these mufflers their great performance and the deep, throaty, instantly recognizable sound you expect from your Harley-Davidson Touring motorcycle. There are also no visible outer screws, providing a sleek, stylish look.

• Black finish

• 4" round muffler

• Rolled scalloped tip that matches an inner core mirrored with the same scalloped shape

• Inner tip is part of the constant velocity, tuned core that gives the muffler its great sound and performance

• Spiral louvered cores deliver specific acoustic tuning producing a distinctive rumble under acceleration and a gruff growl on run down

• No unsightly external screws holding in the tip or core gives a smooth undisturbed finish

Great sounding pipes easy to install
October 22, 2021
Definitely value for the money! Took only an hour to install and boy, what a BIG difference from the stock mufflers. The sound is so GOOD and of course the power and throttle response, as if was suffocating before not until the 909 twins!!!

Gave my Harley the deep sound of a Harley and just loud enough.
