- Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximize capacity and incorporates a resonance chamber for managing sound and increasing usable power. - RS-12's unique profile also provides more clearance for tire and brake caliper.
- Unique oval manifold design was created using FEA process (Finite Element Analysis) and produced using state-of-the-art hydroforming process
- Improved performance gains, weight reduction and fit when compared to previous generation design
- Just like the works systems our Factory Racers use, RS-12 systems utilize precision machined joints. Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance
