New for Milwaukee Eight's, this NH-Series 4-inch muffler with dual cut tip is in a class of its own.
The NH series designation on this 4-inch muffler indicates it is part of the Neighbor Hater class of exhaust. That means it's a bit louder than our standard offerings. It produces that deep rumble you expect, but with a more emphatic level. It has the same sound as our original Neighbor Hater, but in a more sophisticated design. Its machined, dual-cut tip gives this muffler a high-class look to match its roar. Available in chrome or black with black tip.

Heat shields included
Made in the U.S.A.
For 2021-later EU Softail/Touring models, the O2 sensor eliminator plug is required (see accessories)
Tech Tip:
Pre-2021 USA mufflers on a 2021-up EU Softail/Touring?
2021 and later US models only have 2 O2 sensors in the manifolds. 2021 and later EU models (Euro 5 system) have a total of 3 or 4 O2 sensors, also 1 or 2 downstream in the muffler(s) or cross-section balance pipe.
Therefore 2021-2024 US exhaust systems will not fit 2021-2024 European models.
The O2 Eliminator Plug (see accessories) allows the 3rd downstream muffler O2 sensor to be disabled, without triggering fault codes.
This will allow the use of pre-2021 US or European exhaust mufflers that do not have a downstream O2 sensor connection.
