Determining the "best" exhaust for a KTM motorcycle, such as the Duke 390, can be subjective and dependent on personal preferences. Different exhaust systems offer various sound profiles, performance gains, and aesthetic appeal. It's important to consider your specific requirements and desired outcome when choosing an exhaust.
Some popular aftermarket exhaust brands for KTM motorcycles include Akrapovič, Arrow, FMF, and Yoshimura, among others. These manufacturers offer a range of exhaust options designed specifically for KTM bikes, providing performance enhancements, weight reduction, and altered sound characteristics.
When selecting an exhaust, factors to consider include:
Sound: Determine the sound profile you prefer—some riders prefer a deep and aggressive exhaust note, while others prefer a milder tone.
Performance: Look for exhaust systems that offer improved power delivery and torque throughout the RPM range. Some exhausts may also provide weight reduction and enhanced throttle response.
Quality and Fitment: Ensure that the exhaust system is well-made, durable, and specifically designed for your KTM model. It should provide a proper fit and easy installation.
Aesthetics: Consider the visual appeal and design of the exhaust. Different options are available, including various finishes and styles, such as slip-on or full systems.
To make the best choice, it's helpful to research customer reviews, consult with motorcycle enthusiasts or KTM owners' communities, and possibly even listen to sound clips or watch videos showcasing different exhaust options for your specific KTM model. Ultimately, the "best" exhaust is the one that aligns with your preferences and meets your desired performance and aesthetic goals.
