These NH-Series 4-inch mufflers with dual cut tips are in a class of their own. They are a version of our NNEIGHBOR HATERS™ muffler which are not for the faint of heart. These are an aggressive slip-on muffler, for those who think too loud just isn't quite enough. They have to look great and sound good too. Good and loud!
The NH series designation on this 4-inch muffler indicates it is part of the NEIGHBOR HATERS™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 HATERS™, 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.

The state of California considers aftermarket exhaust systems to be legal replacement parts for non-catalyst equipped motorcycles and/or if slip-on mufflers are installed downstream of the OEM catalysts.
California does not allow the use of aftermarket systems that remove original equipment catalysts, (except for racing use only) unless the Air Resources Board has issued an Executive Order for that system.
