The Kawasaki Vulcan 900 is a cruiser known for its reliability, comfortable ride, and classic styling. One of the most popular modifications for Vulcan 900 owners is upgrading the exhaust system. A custom exhaust can enhance the bike's appearance, improve its sound, and potentially boost performance. However, with so many options available, selecting the best custom exhaust for your Vulcan 900 can be a daunting task. This guide will walk you through the key considerations, different types of exhausts, and top brands to help you make an informed decision.

Why Upgrade Your Kawasaki Vulcan 900 Exhaust?

Before diving into specific exhaust options, let's explore the reasons why you might want to upgrade your Vulcan 900's exhaust system. The stock exhaust, while functional, often leaves something to be desired in terms of sound and aesthetics.

• Enhanced Sound: This is often the primary motivation for upgrading. Many riders find the stock exhaust note too quiet and anemic. A custom exhaust can provide a deeper, more aggressive rumble that enhances the riding experience and makes your presence known on the road. A louder exhaust can also improve safety by making you more audible to other drivers.
• Improved Aesthetics: The stock exhaust, while functional, isn't always the most visually appealing. Custom exhausts come in a variety of styles, finishes, and designs, allowing you to personalize your bike's appearance and create a unique look. Whether you prefer a classic chrome finish, a sleek blacked-out look, or something more modern, there's an exhaust system to match your taste.
• Potential Performance Gains: While not always the primary reason for upgrading, a custom exhaust can improve your bike's performance. The stock exhaust systems are often designed with noise reduction and emissions in mind, which can restrict exhaust flow. A high-performance exhaust can improve exhaust flow, potentially leading to small gains in horsepower and torque. However, it's important to note that significant performance gains usually require additional modifications, such as a fuel controller or air intake upgrade.
• Weight Reduction: Some aftermarket exhaust systems are lighter than the stock exhaust. This can contribute to improved handling and overall performance. While the weight savings might not be dramatic, every little bit helps.

Key Considerations When Choosing an Exhaust

Choosing the right exhaust system involves careful consideration of several factors. Here's what you need to keep in mind:

• Sound Level and Tone: Exhaust sound is subjective, so what sounds great to one rider may be annoying to another. Think about the type of sound you're looking for. Do you want a deep, throaty rumble, a loud and aggressive roar, or something in between? It's a good idea to listen to sound clips of different exhausts before making a purchase. Also, consider local noise regulations, as some areas have restrictions on exhaust noise levels. Be mindful and respectful of your neighbors.
• Style and Appearance: The exhaust should complement the overall look of your bike. Consider the finish (chrome, black, etc.) and the design of the exhaust. Some exhausts are long and sleek, while others are short and aggressive. Think about the overall style you are trying to achieve and how the exhaust will fit into that vision. Do you want it to blend in or stand out?
• Performance: If performance is a major concern, look for exhausts that are designed for improved flow. These exhausts often have larger diameter pipes and less restrictive mufflers. However, keep in mind that you may need to make other modifications to fully realize the performance gains. A fuel controller, for example, may be necessary to adjust the fuel mixture to compensate for the increased airflow.
• Installation: Some exhausts are easier to install than others. If you're comfortable working on your bike, you may be able to install the exhaust yourself. However, if you're not mechanically inclined, you may want to have a professional install it. Consider the complexity of the installation process and your own skill level before making a decision. Some exhausts require cutting or welding, while others are a simple bolt-on replacement.
• Price: Exhaust systems can range in price from a few hundred dollars to over a thousand. Set a budget before you start shopping and stick to it. Keep in mind that the price of the exhaust is not always indicative of its quality or performance. Do your research and read reviews to find the best value for your money. Factor in the cost of installation if you plan to have a professional do the work.
• Quality and Durability: Choose an exhaust from a reputable brand that uses high-quality materials. The exhaust will be exposed to the elements, so it needs to be durable enough to withstand heat, moisture, and road debris. Look for exhausts made from stainless steel or high-quality chrome. Read reviews to see how other riders have fared with the exhaust over time.

Types of Custom Exhausts for the Vulcan 900

There are several different types of exhaust systems available for the Kawasaki Vulcan 900, each with its own unique characteristics:

• Slip-On Exhausts: These are the simplest and most affordable type of exhaust upgrade. They replace only the muffler, leaving the stock head pipes in place. Slip-ons are easy to install and can provide a noticeable improvement in sound and appearance. However, they typically offer minimal performance gains.
• Full Exhaust Systems: These replace the entire exhaust system, from the engine to the muffler. Full systems offer the potential for greater performance gains compared to slip-ons, as they allow for optimized exhaust flow throughout the entire system. However, they are more expensive and more difficult to install.
• 2-into-1 Exhausts: These systems combine the exhaust gases from both cylinders into a single pipe. 2-into-1 exhausts can offer improved performance and a unique look. They are often favored by riders who want a more aggressive sound and a more streamlined appearance.
• 2-into-2 Exhausts: These systems maintain separate exhaust pipes for each cylinder. 2-into-2 exhausts offer a classic look and can provide a balanced sound. They are often favored by riders who want to retain the traditional cruiser aesthetic.

• Use Anti-Seize: Apply anti-seize compound to the threads of the new exhaust bolts. This will prevent them from seizing in the future.
• Torque to Specification: Use a torque wrench to tighten all the bolts to the manufacturer's specifications. This will ensure that the exhaust is properly secured and that you don't damage the threads.
• Check for Leaks: After you install the exhaust, start the bike and check for exhaust leaks. If you find any leaks, tighten the bolts until the leaks stop.
