Factory expansion chamber

Developed in-house, these headers have a minimalist look that reflects the high standards set by our factory riders.
Benefits:

• Fat torque curve for optimal rideability
• Minimal weight and maximal performance
• Made from rugged steel
• Untreated surface for an unadulterated factory look
• Rich, unmistakable sound

We recommend combining them with the factory or Six Days silencer for a perfectly tuned and performance-optimized system.
