KTM aftermarket 390 motorcycle exhausts

Why Upgrade Your KTM Motorcycle Exhaust? Why even consider swapping out your factory KTM muffler? An aftermarket exhaust is the ultimate way to shed unnecessary bulk and unleash the full potential, performance and sound of your machine.

By optimizing exhaust gas scavenging and refining the signature KTM growl, you achieve a superior power-to-weight ratio. When integrated with a dedicated race map, it bypasses the lean factory fueling required for emissions compliance—eliminating low-end jerkiness and providing the razor-sharp, responsive throttle delivery that defines the KTM riding experience.

  • KTM Motorcycle Exhausts Shed the Weight: Replace heavy OEM silencers with lightweight performance materials.

  • Unlock Power: Improve airflow to maximize horsepower and torque.

  • Signature Sound: Achieve a deeper, more aggressive KTM exhaust note.

  • Precision Fueling: Use a race map to eliminate “lean” factory stutters, ensuring buttery-smooth throttle response in technical sections.
