A Basic Guide To Aftermarket Motorcycle Exhaust Systems

One of the effective ways of improving your bike’s performance and boosting its style and appeal is upgrading to an aftermarket motorcycle exhaust system. Aftermarket pipes are designed with more efficient flow dynamics to help extract more power from your engine.

But before you hop in, it’s essential that you ensure that the shiny new system is the right fit for your bike. You should also consider an efficient emission system like REP Gaskets to take care of toxic emissions from your motorcycle. However you do it, here’s a guide to help you understand and be familiar with the aftermarket motorcycle exhaust systems:

S&S Cycle has stock replacement and race exhaust systems, as well as turbo kits for a growing number of UTVs. Listen to them at www.sscycle.com.

What Do Aftermarket Motorcycle Exhaust Systems Do?

They’re designed to improve performance, sound, and style. They can also reduce weight by replacing the stock exhaust system with a lighter one. This can make your bike faster and easier to handle, especially on tight trails or traffic.

They may also improve fuel economy by reducing back pressure or increasing engine power output. Reducing back pressure allows more air into the cylinders. This is where it mixes with fuel before it’s pushed through the cylinder wall to generate higher speed, increasing engine power output.

To summarize, a well-designed aftermarket motorcycle exhaust system can help improve the performance of your motorcycle, and reduce emissions, noise pollution levels, and back pressure while maintaining compliance with local noise laws where required.


Why Upgrade To An Aftermarket System?

There are many reasons to upgrade to an aftermarket exhaust system, including:

  • Better Sound

A high-quality aftermarket exhaust system can give you a deeper tone that sounds better and is more pleasant to listen to at higher speeds.

  • Better Performance/Fuel Economy

High-quality aftermarket systems offer superior power delivery. It offers better acceleration performance when accelerating from low speeds. A custom motorcycle exhaust will improve performance by increasing horsepower and torque, making the engine smoother. The system also helps conserve fuel since your engine is well managed and isn’t churning out your oil.

  • Improved Durability

Aftermarket products are generally built with better materials than their stock counterparts. As such, they’re more durable and last longer without breaking down. They also tend to be lighter than stock units, which means you can save on fuel consumption when upgrading.

Types of Aftermarket Motorcycle Exhaust

One of the common types of aftermarket motorcycle exhaust systems is a straight pipe. Straight pipes have no mufflers or other restrictions, so they can be super loud and often illegal to use on public roads. They’re also usually very cheap and straightforward to install.

Another popular choice is the dual exhaust system, which uses two separate pipes leading away from each cylinder head instead of one large piece like straight pipes. The benefit here is that you can customize how loud you want your bike’s exhaust note by adding different size mufflers or resonators in the front of each pipe. This lets you adjust how much sound it produces.


Which Material Is Best For Aftermarket Exhausts?

Aftermarket exhausts are available in a variety of materials. Although each material has many benefits, they vary in durability, weight, and efficiency. Some of the best materials include:

  • Aluminum Alloy: The most common material is aluminum alloy. This is because it’s light and durable so that the exhaust will last longer. It also welds to other parts of your bike, although its corrosion resistance is poor compared to stainless steel.
  • Stainless Steel: The second most common material is stainless steel. Stainless steel is heavier but more substantial than aluminum and less likely to crack or break under pressure. It doesn’t corrode easily but will eventually rust if it repeatedly comes into contact with water.
  • Cast Iron: Cast iron is durable and relatively inexpensive but heavy. It also requires frequent maintenance due to its porous nature and tendency to rust.

While there are other materials, the three mentioned above are common and deemed reliable and efficient. They’re especially great for reducing energy and noise.


Can I Install An Aftermarket System Myself?

Yes, you can. You’d need some essential tools like a torque wrench, hacksaw, wire brush, etc. You’d also need to follow the guide from the manual. However, it’s always advisable to hire an experienced mechanic for installation.


There are many options for aftermarket motorcycle exhaust systems, and it can be hard to pick the right one. To start, you can think about how much noise is acceptable in your environment before deciding. You should also consider the area you’ll ride your bike in because if you’re prone to bumping into puddles, you’d want to go for one capable of withstanding extreme conditions.
