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!

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.

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!

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.

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!

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.

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.

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.

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.

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.

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

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.

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.
