Cobra

Cobra Neighbor Hater Slip-On Exhaust

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. Each muffler starts as a round 4-inch tube, then bell out to 4.5-inches. It presents an aggressive and classic design at the rear. The muffler tip is then rolled to give it a clean, finished look. Internally, these NH mufflers have a perforated core with strategically spaced holes. 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.

  • Almost loud enough to wake the dead
    • Paired with a set of Cobra headers (sold separately), you will wake the dead
  • Comes with all required installation hardware and easy-to-follow instructions
  • Sold in pairs
  • Made in the USA

I ordered these Slip-On pipes for my 2017 Harley-Davidson Road King. You will need a 1/2, 9/16, & 5/8 socket to take off the stock pipes. And to mount the pipes. I hade the pipes on in 21 minuets. I used mechanic gloves to protect the pipes. It was fast and simple. They sound amazing. My Girl rides a 08 Harley-Davidson Softail Deluxe. She has the VH Long shots. They sound very close to hers. But these sound better rolling. I give it a 10 a freaking 10. LOL.

Installed them on a 2015 HD Limited and it immediately improves the look of the bike. The install is easy and straight forward, just make sure you get the clamps completely out of the way when you take off the stock mufflers. Sounds is a deep rumple, like the sound of distant thunder. Very nice. Not too loud. Had V&H Shortshots on a Sportster 48 before and these are not even close to being as obnoxiously loud as those were. But the Cobra's are noticeably louder than stock and have this nice dark tone to them. Desired improvement and I am very happy with the result.

Great sound for the touring bikes, nice deep rumble at idle, but can still hear the radio, shipping was super fast and super good service from parts giant. They were showing "out of stock " on the site so I called, the guy put me on hold for a few minutes and went to "lay my hands on them" so I got them shipped that day, no shipping, to my front door because that young man actually tried to help me instead of just saying "they're out" so bravo, that my friends earns my business. Not to mention they're about 30 bucks cheaper than any other site. I would highly recommend.

I can’t even begin to tell you how long I was researching slip on exhausts with Harley’s ‘17 and ‘18 warranty void BS. I was extremely cautious to purchase a slip on in fear of it sounding cheap and wimpy. I wasn’t able to find anyone who had slip ons to heat in person and based my decision solely on YouTube videos. I can’t even express how great these sound. Deep and throaty much better looking and sounding than the stock by far and the best price. A+ would recommend until you get a full exhaust!

I don't know if the 1 or the 5 is the highest rating. Whichever is the highest is the one I want. I ordered my Cobra Neighbor Haters on Sunday and I got them on Tuesday. The quality is outstanding and the sound is perfect. These are on a 2018 Harley Street Glide. The price is really cheap. No problem putting them on. I am extremely happy with my purchase.

Questions & Answers

  • These fit 2018 Milwaukee eight?

    By: Princess

    Yes, these Neighbor Hater mufflers from Cobra will indeed fit 2018 Milwaukee 8 models. Just choose your exact model and year from our fit guide and we'll send the proper slip-on mufflers to fit your machine!

    By: Staff

  • What's needed for tuning ?

    By: Guest

    For older bikes with a carb, such as the 1995 FLHR - yes, you'll want to adjust the carburetor in order to be sure the bike runs correctly. To do that, you'll need a Dynojet Carburetor Jet Kit as that will include everything you need to ensure proper fuel delivery for your carbureted bikes.

    For fuel-injected bikes, and this applies to most slip-on exhausts - the OEM ECU can handle the changes in exhaust flow with ease. That is to say, as long as the bike is fuel-injected, you don't need to adjust fuel delivery in any way.

    By: Staff

  • Would these fit 06 Streetglide with vanve n hins true dual headers???

    By: John

    Yes, these mufflers should fit that exhaust without issue since the True Dual headers are designed to work with the stock mufflers. You should have no problem fitting the Neighbor Haters to your Vance & Hines True Dual headers. Just be sure to select your exact bike from our fit guide and you'll be all set!

    By: Staff

  • Will.these for a 2016 ultra classic

    By: Keith

    Yes, Cobra does indeed built a set of Neighbor Haters to fit the 2016 Ultra Classic!

    Just select the 2016 Harley Davidson FLHTCU Ultra Classic Electra Glide from our fit guide and you'll get the correct Neighbor Haters to fit your machine.

    By: Staff

  • i have a 2017 RGS with stock exhaust, can i just replace with NH slipons. I have a V&H fuelpac3 also with autotune

    By: Ellis

    Since you've already got the Fuelpak FP3 on your Road Glide Special, you've got everything you need to run the Neighbor Hater slip-ons. Just use the FP3's auto tune function after you put these mufflers on, burn a tank of gas through the bike out on your favorite roads, and then flash over the suggested changes. Once you've done that, you're all set!

    By: Staff

  • How loud are these neighbor haters by cobra?

    By: David

    Unfortunately, Cobra doesn't provide any information in regard to sound output values.

    I can tell you that these will indeed be louder than stock, just on their own. But, if you really want sound, you must pair them with a set of Cobra headers. With those two combined, the NH pipes are going to be about as loud as you can get from an aftermarket exhaust system.

    By: Staff

  • Do I need a tuner to run these on a stock 2017 street glide?

    By: Rusty

    So long as your bike is completely stock, the OEM ECU can usually handle the change in exhaust flow with this exhaust. It's when you go from a stock set up, or a setup with slip-ons, to a full exhaust system and/or you put an aftermarket air cleaner on your bike, that you need to adjust fuel delivery.

    That said, if you're riding mostly at high altitudes or in an area with poor fuel quality (not usually a problem in the USA!), then yes, you'll want to adjust fuel delivery to suit. To do that, we can't say enough good things about the Vance & Hines Fuelpak FP3 Autotuner for the 2017 Harley Street Glide. It's simple to install and use, plus the included instructions explain exactly how to configure the device to fit your needs without a trip to the dyno. All you need is an Android or iOS smart phone and the free FP3 app and you're all set to use that tuner.

  • Will they fit a 2014 ultra limited with 103 engine

    By: Jake

    Yes, if you were to choose the 2014 Harley Davidson FLHTK Electra Glide Ultra Limited Cobra Neighbor Haters from our fit guide, you'd receive the correct exhaust to fit your machine.

    By: Staff

  • 2015 103 street glide. With just the mufflers alone will I have a noticeable Cobra sound ?

    By: Jerry C

    As these mufflers were specifically engineered to annoy the non-riding public, you'll definitely notice a change in the note coming from the rear of your bike. And, if you were to pair them with a set of Cobra Power Port Head Pipes, yeah - people are going to notice, everywhere.

    By: Staff

  • Does this come as a set or individual?

    By: Black Jack

    These mufflers are sold in pairs. You only need to purchase a quantity of one in order to completely outfit any machine listed in our fit guide.

    By: Staff

  • Can the baffles be taken out of these slip ons

    By: Guest

    Yes, all Cobra Neighbor Hater exhausts are fitted with removable baffles.

    By: Staff

  • I have a 2014 Street glide special with vance n hines pipes. They aren't as loud as I'd like. My question is, are the baffles easy to take out of the cobra NHs?

    By: Guest

    If the current pipes on your bike aren't loud enough, Neighbor Haters are up to the task! Removing each baffle is easy, as they're only affixed with a bolt. For those of you putting these on for the first time, please be sure to put some anti-seize on the baffle bolts, to make it easier for removal later on.

    Mind you, the baffle is part of the bell-shaped portion at the end of the muffler. So you will be changing the look of the outlet end of your exhaust.

    By: Staff

  • After reading the answered questions I belive that I have an idea, but to make sure. If I add these and the stock headers on my new 2018 Road King do I have to get a tuner?

    By: Jay

    In the case of the 2018 Road King Cobra Neighbor Haters, you probably won't need to buy a fuel tuner if you're only fitting these mufflers to your bike. There are, of course, exceptions to this rule. If you're in an area that has sometimes questionable quality fuel, or you do most of your riding at higher altitudes, then you'll probably want to look into some tuning options. Otherwise, if you spend most of your time below 5,000 feet and live in the USA, you should have no need to adjust fuel delivery with only these mufflers installed.
