The new Neighbor Hater Mufflers by Cobra are not for the faint of heart. These are an aggressive slip-on muffler, for those who think loud just isn't good enough.


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 perforated, 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.
