How Do Different Exhaust Systems Impact Performance on the 955i?

Different exhaust systems significantly impact the performance of the 955i by influencing factors like power output, weight, and sound.

• Stock Exhaust: The original exhaust system is designed for compliance and noise regulation, which may limit performance.
• Aftermarket Slip-On Exhaust: These systems are popular for enhancing sound and aesthetics while providing a moderate performance boost.
• Full Exhaust System: A complete replacement that includes headers and mufflers, offering the greatest potential for horsepower and torque improvements.
• High-Performance Race Exhaust: Specifically designed for racing, these systems prioritize weight reduction and maximum flow, significantly increasing performance at the expense of noise and emissions compliance.
• Cat-Delete Exhaust: By removing the catalytic converter, this option maximizes exhaust flow, leading to increased power but is typically illegal for street use due to emissions regulations.

The Stock Exhaust is the factory option that balances sound, performance, and regulations. While it meets legal standards, it often restricts airflow, limiting the engine’s potential.

Aftermarket Slip-On Exhausts replace only the muffler section, allowing for better sound and reduced weight without the need to change the entire system. They can offer a moderate increase in horsepower and a more aggressive exhaust note, making them a popular choice for casual riders looking to enhance their bike’s character.

A Full Exhaust System involves replacing both the headers and the muffler, resulting in the most significant gains in horsepower and torque. This option provides optimal exhaust flow, but installation can be complex, and it may require tuning for best performance.

High-Performance Race Exhausts are designed for maximum performance, often at the expense of noise levels and emissions compliance. These systems are typically lighter and allow for the greatest exhaust flow, making them suitable for competitive environments but less ideal for street use due to noise regulations.

Cat-Delete Exhausts remove the catalytic converter entirely, which can lead to significant power increases by reducing back pressure. However, this modification is generally illegal for street use due to environmental regulations, making it more suitable for race applications or track days.

What Factors Should You Consider When Choosing an Exhaust for the 955i?

When choosing the best exhaust for a 955i, several factors should be considered to ensure optimal performance and satisfaction.

• Material: The type of material used in the exhaust system significantly affects weight, durability, and corrosion resistance. Stainless steel is a popular choice due to its strength and resistance to rust, while titanium is lighter and offers enhanced performance but at a higher cost.
• Sound Characteristics: Different exhaust systems produce varying sound profiles, which can greatly impact the riding experience. Some riders prefer a deep, aggressive tone, while others may opt for a quieter system to reduce noise pollution and maintain a more subdued ride.
• Performance Gains: It’s essential to consider how the exhaust system will affect engine performance. A well-designed exhaust can improve horsepower and torque by optimizing exhaust flow and reducing back pressure, making it crucial to choose one that complements the engine’s characteristics.
• Compatibility: Ensuring that the exhaust system is compatible with the 955i is vital for proper installation and function. Check for fitment issues, such as mounting points and clearance with other components, to avoid complications during installation.
