COOBER is excited to bring you our catalytic converter delete for the KTM 390 Adventure, 390 Enduro, and 390 SMC-R!
Features:
- High-Quality Materials: The header is crafted from lightweight, durable stainless steel, ensuring longevity and resistance to corrosion. This material also helps optimize heat dissipation, improving overall engine efficiency.
- Decat Design: The removal of the catalytic converter allows for improved exhaust flow, which translates to a noticeable increase in horsepower and torque. Despite the decat design, COOBER ensures that the system remains stable.
- Improved Performance: With enhanced exhaust gas flow, the decat header boosts throttle response, mid-range power, and overall engine performance. This makes it an ideal upgrade for spirited riders and enthusiasts.
- Enhanced Sound: The COOBER header provides a deeper, more aggressive exhaust note without excessive noise, preserving the balance between style and practicality.
- Direct Fit: Designed specifically for the KTM Duke 390 and Husqvarna 401 models, the header is a direct fit and integrates seamlessly with the stock exhaust system or most aftermarket slip-ons.
