KTM RC 390 & 390 DUKE Gen 2 Titanium Exhaust System 

Single O2 Sensor model

390 RC Gen 2                                   2022-2025

390 DUKE Gen 2 Only                    2022-2023 (Not Gen 3 Euro 5+ 2024 On) 

This exhaust system is engineered to meet World Supersport 300 standards, delivering serious performance gains and noticeable weight savings. Choose the high-mount slip-on muffler to pair with your OEM headers and catalytic converter, or unleash the full potential with the four-step tapered titanium header, designed to eliminate the catalytic converter for maximum flow.

The inboard high-mount design keeps the exhaust tucked safely away to reduce damage during a fall, ideal for competitive track riders, and it looks incredible on the street. Thanks to its spring-mounted setup, the muffler can be fitted or removed in seconds, making it perfect for race-day efficiency.

Built with a straight-through, unrestricted design, the muffler includes a removable DB killer to help manage noise levels. Keep in mind that the system may not comply with Euro noise regulations. A DB killer insert and carbon heat shield are included to complete the package.

ALL MOUNTING HARDWARE SUPPLIED.
