Cobra GEN2 4" Neighbor Hater Slip-On Mufflers Black


Hard to believe, but Cobra made the Neighbor Haters sound even better. Each second generation Neighbor Hater starts with a 4-inch round black steel sleeve muffler body fitted with a black machined aluminum end cap that features an outer tip with dual grooves. Black Neighbor Hater tips have a gloss black finish on the inside. Each inner tip echoes the O.G. Neighbor Hater formula by creating a strong visual resemblance and an exceptional sonic BOOM that made the original Cobra NH mufflers famous!

Customer Reviews


Gen 2 Neighbor haters

By Jimmy R. on 

Nice sound, great look.


Great pipes

By None on  Verified Purchaser

Great set of pipes, exactly as described, installed in about half an hour including removal of the existing ones, perfect fit for my 2023 road king special. Sounds great! Looks fantastic! A+++


Nice looking pipes

By D G on  Verified Purchaser

I have 2023 street glide. They look great but not much loader than the stock pipes. They have a deep tone. I took the baffles out and they sound much better.


Cobra mufflers

By Robert H. on  Verified Purchaser

Sound is very good much better than stock mufflers.


2024 Road King

By Seth J. on  Verified Purchaser

Put these on my 2024 Road King. Easy install and they sound great.


Great Sound! Great Looks!

By Roger A. on  Verified Purchaser

Thes slip ons look and sound great! Finished off my complete exhaust replacement for original stock on my 2014 Ultra Limited! Cobra Power Port True Duals and the Fi2000 PowerPro Black to make it all sing in harmony!


Fit and finish is perfect

By Corey K. on  Verified Purchaser

Sound is low, however it's better than stock and after warranty has expired paired with cobra headers should get er done!


Great quality

By Jason K. on  Verified Purchaser

Amazing sound, great quality!


Great pipes, take out baffles

By Michael T. on  Verified Purchaser

The pipes look great but sound like stock. I'm going to have to take the baffles out. Do yourself a favor and take them out ahead of time to save your money, Harley labor isn't cheap.


Completely satisfied

By Quinn F. on  Verified Purchaser

Completely satisfied with the mufflers. Sound good so far. Once they burn in, they will sound like they should. Time will tell. Took about 25 minutes to do both sides. No issues at all.


Cobra 4.5s

By Chuck A. on  Verified Purchaser

Easy to install. Much better than stock pipes. Thought they might be a little louder but love the sound the 4.5s sing out.

Questions & Answers


Would these fit a 2023 street glide special 114

By Anon.

Yes, if you were to choose the 2023 Harley Davidson FLHXS Street Glide Special slip-on exhaust from our fit guide, you'd receive the correct mufflers to fit your bike. They'll bolt straight in place of the stock mufflers in about five minutes. It's a really easy installation.

By Tom

Will these slip ons work with the pro chamber headpipe

By Mark D.

Oh yes, these would be a perfect match from Cobra's Pro Chamber headers!
