If you do not want to change the full exhaust, or you do not want to pay too much money, then Sharkroad will do the trick. It is always good to do a tune, but it is not always necessary, for example, this particular slip-on does not need it. Let us talk a little about the performance of the slip-on, you might notice a little bit of loss on the lower ends of the revs. To be more exact, first, second and third gear might have a little bit of loss of power.

You do not have to worry about it too much as it makes up for it towards the mid-range when you are all the way open. To prevent losing that low end, you can put an air cleaner on there or an intake and then put the tune on the bike. This whole process will cost less than the full exhaust and is easier to install. The installation process is a big problem most of the time, so easy installation is the selling point for Sharkroad.

We have not mentioned the actual sound of the slip-on. They deliver the right sound, as they are not very powerful, which will give you a headache, but are not so quiet that will make buying the slip-on a bad decision.

With this slip-on, we can guarantee that the bike’s appearance will not get touched.

Guide To Buy Exhaust For Milwaukee 8

Before we start the review, let us take a little guide to help you find the loudest exhaust for Milwaukee 8.

Sound, If you are looking for just sound and a very mild performance increase, maybe potentially a different ornamental look, stage one is a good option.

Everybody has a little different idea of what they prefer in the sound of their exhaust system. If you want the bike to be a little louder and you are not looking for a huge performance increase, then you can do the slip-on mufflers. It is the cheapest if you want just the benefit of a different sounding and you don’t want to spend a lot of extra money on additional tuners.

Performance, To take it a step further, what you can do is to go to the exhaust system, or you can switch out the header pipe and merge that with a muffler of your choice as well, but in that position, it is crucial to find the best head pipe for Milwaukee 8. If you decide to go to the exhaust system, you will need to put an additional tuner there.

Ecology, With the environment in the position that it already is, the key is to choose an eco-friendly exhaust systemWith Milwaukee 8 there are catalytic converters, which is a device that decreases toxic gasoline from an inner flaming engine into less-toxic pollutants by catalyzing a redox reaction. Anytime you remove that equipment, you are now officially polluting the environment, which is illegal in some US states. The most strict state about these rules is California, where most influential manufacturers of mufflers have gone through the certification process. On the terrain motorbikes, you have to stick to mufflers on the soft tails.

The Davidson has Screamin Eagle mufflers for all the soft tails, and they have the catalytic converters in there for the appropriate models. A lot of people have been saying that Screamin Eagles do not get quite the exhaust note or the volume that most people are hoping for, but they have made some pretty big steps for development in the past couple of years.

Additional Features:

  • Sound Customization: Tailor your bike’s sound with various options, from mild to louder profiles.
  • Performance Enhancement: Upgrade beyond the stage one option by replacing the header pipe and muffler for improved performance.
  • Eco-Friendly Consideration: Navigate through catalytic converters and adherence to environmental regulations, especially in strict states like California.
  • Manufacturer Options: Explore Screamin Eagle mufflers and their compliance with emission standards.

Performance EnhancementHeader pipe and muffler upgrades

It all comes down to your preference and the exhaust tones. You got to listen to all of the exhausts to know which are louder or have a higher pitch. To be specific, there are some of the best systems: Reinhardt’s, Cobra, Vance & Hines, and many more.

Harley Street Glides are lighter than Harley Road Glides, so some of the exhaust systems you think are the best for Road Glide might not work on Street Glide. For them, one of the best exhausts is Cobra True Dual Head Pipes 6250.

If you want to get the full benefit of the performance improvement, you need to change an exhaust system. If you are a person, who wants to go for the only sound, you can get away with just putting a muffler on your bike, but you are not going to get any performance increase. You are just going to get the sound, and but it will not operate to its optimum. It will not run poorly significantly, but you will not get any performance benefit at all.

When you are changing out your exhaust system, there are two things you can do. The first thing you can do is change out your muffler, keep the same stock header pipe on your motorbike and change out the slip-on muffler portion of the exhaust system. Generally, if you find the best header for Milwaukee 8, you will get anywhere from about a thirty to fifty percent sound increase.


Exhaust is not something you might think is an important part of the motorbike, but in reality, you are wrong. Some things make the bike a great one, for example, if you are a real lover of bikes, I am pretty sure that you love the sound of the bike more than anything! It does not matter how your bike sounds, if it has the wrong exhaust, it all goes to waste.

The average motorcycle is primarily ten times more polluting per mile than a passenger car, light truck, or SUV, so the right exhaust is crucial for the environment. The sound is not the only thing that is important regarding the bike. They will also increase the performance of the motorbike. Hopefully, it is the article that helped you find the best exhaust system for Milwaukee 8. Related Harley Davidson, 4 Channel Amp For Harley Davidson
