Cobra Chrome NH(Neighbor Hater) Series Mufflers - 6107

Our Neighbor Haters are not for the faint of heart. These are an aggressive slip-on muffler, for those who think loud just isn't good enough. They have to sound good too. Good and loud.

  • These mufflers 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 a spun and louvered baffle, but only for 8-inches.
  • This is done in order to produce 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.


Included Items:

(2) Chrome steel mufflers W/removable baffles

The NH series is a good option for an HD bagger
I am one of the riders who not only wants to hear my motor, but ensure others can hear me when its necessary. The NH series is not as loud as I expected, but it is an aggressive mufffler with a solid growl. Performance is better than I expected and when you twist the wick, it responds very well.
This is an outstanding product at a very good price.

Great pipes for a great deal!
DK shipped them fast. The pipes are beautiful, I have had them on for 2 days and have gotten a lot of compliments. They gave a deep growl, deeper than VH. You will have to turn your stereo up but the pipes are not obnoxious. It's a loud that you feel in your chest not a loud that hurts your ears. My head pipes are oem.

Awesome sounding slip-ons, and very quick delivery
The slip-on mufflers were a breeze to put on. The sound is exactly what I wanted. It's very loud but not too loud(will be heard like the saying goes loud pipes saves lives.) I would highly recommend these cobra NH Slip-on!! Also the delivery was very very quick, I would definitely order from Dennis Kirk again a customer for life.

These slip ons are simply amazing. Great sound for a fraction of the cost. Matched them up with the Fi2000 fuel programmer and high flow KN air intake...unbelievable. Shipping was quick and packaging is top notch. 2009 Harley Davidson Ultra Classic super easy install. Fuel programmer directions said to prop up the fuel tank with block of wood so you can get at injectors...Don't waste your time, take the tank off. This is how a Harley should sound, slip ons are truly amazing.
