Description
Unleash the true potential of your ride with the M4 Performance GP Series Slip-On Exhaust in the coveted “Black Series” finish. Designed for riders who refuse to compromise on style or performance, this muffler replaces your heavy, restrictive stock exhaust with a race-inspired, free-flowing system.
Aggressive Styling & Stealth Finish Gone is the standard chrome; this unit features a sleek, high-temperature matte black coating that blends seamlessly with modern frame and engine components. The iconic chrome M4 badge provides a striking contrast, signaling high-quality American engineering.
Signature Sound & Performance Don’t just be seen—be heard. The M4 GP Series is famous for its deep, throaty exhaust note that screams performance at high RPMs. Engineered to improve gas flow, this slip-on helps unlock throttle response and mid-range torque while shedding significant pounds from your bike to improve handling.
