Choosing a Suitable Exhaust Upgrade for Your Motorcycle

When considering an upgrade for your motorcycle's exhaust system, it's crucial to weigh the benefits against the potential drawbacks, especially in terms of engine performance and local regulations. In any renowned motorcycle magazine, you might come across testbed tests that often reveal that aftermarket exhaust systems tend to cut down on power. This leads to the question: how do you navigate the decision-making process?

Understanding the Purpose of an Exhaust Upgrade

There are several reasons one might consider exchanging the original factory exhaust for an aftermarket system. These include:

Cost-effectiveness: If your stock exhaust is damaged, an aftermarket exhaust can be a more affordable solution than buying a replacement part from the factory. This is particularly relevant for older, less expensive motorcycles where the factory spare parts might be pricey. Weight reduction: Some aftermarket mufflers offer lighter options compared to the factory exhaust setup. If you're looking to make your bike weigh less, this is a useful consideration. Market perception: Opting for the loudest muffler might alienate your fellow riders, so this factor must be carefully weighed.

What Constitutes an Upgrade?

When the phrase 'upgrade' is used, it's generally understood that you are changing the exhaust from the one the bike was designed to work with. This often necessitates a remapping of the bike's engine and fuel systems to work optimally with the new setup. Therefore, before you decide on any upgrade, it's essential to have a clear budget and a concrete idea of what you want, such as increased power or a better sound profile.

Types of Stock Exhaust Systems

Stock motorcycle exhaust systems often come in a variety of configurations, from true duals (two into two) to two into one systems. Understanding these configurations can help guide your choice when looking for an aftermarket upgrade. A two into one system can enhance performance by reducing restrictions and improving the flow of gases out of the engine. Manufacturers like Drag Specialties, JP Cycles, and others offer a range of options for such systems. Yoshimura exhaust systems, for example, are known to provide a deeper exhaust note and improved performance.

Considerations Before Upgrading

Weight: Choose a light exhaust system to reduce the overall weight of your motorcycle. Lighter systems can improve handling and fuel efficiency. Restrictions: Opt for a system that is less restrictive to allow smoother gas flow and better performance. However, be mindful of catalytic converters, as they are mandated in some areas to reduce harmful emissions. Local Laws: Familiarize yourself with local regulations concerning catalytic converters and noise levels. A decibel level is typically measured for allowable sound. Ensure that your exhaust system complies with these laws to avoid legal issues.

By understanding the purpose of an exhaust upgrade, considering the different stock configurations, and being mindful of local laws, you can make an informed decision that will enhance your riding experience while staying within regulatory boundaries.
