Developed on the dyno and designed with the bagger enthusiast in mind, Cobra Engineering's newly introduced NH Series mufflers will enhance both the look and sound of your late-model Harley-Davidson motorcycle.

The new NH Series mufflers (for H-D Bagger models) are unlike anything currently available for Harleys. These mufflers not only look intimidating, but also sound intimidating as well. “This NH Series is totally different from what people are used to, especially when they hear the name Cobra,” said Tim McCool, Cobra Engineering President. “Our customers and dealers have been asking us for a more aggressive sounding muffler for quite some time. So we developed the NH Series to meet that demand.”

When developing these mufflers, Cobra did extensive sound and dyno testing. The goal was to build a muffler that looked, sounded, and performed unlike anything else in the market place. What emerged is a 4-inch muffler that has an unmistakable sound, all for a reasonable price.

There’s a whole lot that makes these mufflers different, starting with the overall design. The bodies start as round 4-inch tubes, then bell out to 4.5 inches, for an aggressive and classic design at the rear. The muffler tip is then rolled to give them a clean, finished look. Internally, these NH mufflers have an 8-inch spun and louvered baffle. This limited louvering produces an aggressive bark. At the end of the baffle is a trumpet shaped inner tip that works in harmony with the belled end, creating a unique look. There will also be a quieter core option for those who enjoy the look, but don’t hate their neighbors.

To top it all off, the retail MSRP of the NH Series mufflers is $420, and comes with Cobra's Limited Lifetime Warranty. More info at
