Firstly, determine the goals you want to achieve with your upgraded exhaust system. Do you crave more horsepower and acceleration? Look for exhaust systems designed for increased airflow, often featuring larger pipes. If shedding weight is a priority, consider exhausts crafted from lightweight materials like titanium or high-quality aluminum. Concerning exhaust notes, opt for exhausts with less restrictive mufflers for a throatier, more aggressive sound.
The best material for your exhaust depends on your priorities. If durability and affordability are essential, stainless steel is a solid option. If minimizing weight is your main concern, aluminum is a good choice. But titanium might be the perfect fit if you desire the ultimate in performance and can handle the price tag.
Many aftermarket exhaust systems are designed for a straightforward installation process. Look for options that utilize existing mounting points and require minimal modification to your Xpedition. Some exhaust systems require more frequent maintenance than others. Therefore, consider the maintenance requirements before making your choice.
Slip-on vs. Full System exhausts are the two common types of exhaust upgrades for the Polaris Xpedition and many vehicles. Slip-on exhausts replace the muffler only, offering a simpler installation. Complete systems replace the entire exhaust for maximum performance gains but require more complex installation. Additionally, ensure the exhaust maintains your stock spark arrestor for legal riding on public lands. Some aftermarket exhausts come with a spark arrestor already built-in.
Consider your noise tolerance and riding environment. Some exhaust systems offer a more aggressive sound, while others prioritize a subtle improvement over stock. Exhausts can produce different sound tones, ranging from a deep rumble to a high-pitched snarl. Choose a tone that complements your preference and riding style, but be wary of regulations.
Ensure your chosen exhaust system maintains a spark arrestor to meet local emissions regulations and prevent wildfires. Some areas have noise restrictions for off-road vehicles. Check local laws to ensure your exhaust system falls within allowable decibel and smog levels.
