Unleash the Beast, Silence the Noise : The Ultimate Dual-Tone Exhaust Stop choosing between raw track performance and a neighborhood-friendly exhaust note.
The Universal 51mm Motorcycle Valvetronic Exhaust System gives you total control over your bike's acoustic and performance profile at the press of a button. Designed for riders who want the aggressive scream of a free-flow racing pipe on the open highway but need to fly under the radar in urban environments or avoid strict noise checkpoints, this electronic valve-controlled muffler delivers the ultimate hybrid riding experience. Key Features & Benefits Electronic Valve Switch Control: Easily switch between a refined, quiet rumble and a straight-through racing growl via the premium handlebar-mounted switch or remote control module. Universal 51mm
Fitment: Features an industry-standard 51mm (2-inch) inlet diameter, making it perfectly compatible with a massive range of slip-on setups, headers, and performance mid-pipes. Dual Performance Modes: Beast Mode (Valve Open): Zero exhaust restriction for high-velocity gas flow, maximizing horsepower and torque while unleashing a deep, aggressive superbike exhaust note. Stealth Mode (Valve Closed): Dynamically redirects exhaust gases through a restricted baffled chamber, dampening the sound back to neighborhood-safe decibel levels. Premium Heavy-Duty Build: Crafted from premium corrosion-resistant SS304 stainless steel built to handle intense exhaust temperatures and harsh weather conditions. Optimized Engine Efficiency: Improves low-end torque when closed and sharpens high-RPM throttle response when fully open. Technical Specifications Product Type: Universal Valvetronic Motorcycle Exhaust Muffler Inlet Diameter: 51mm (2 inches) Control Mechanism: Fully electronic actuator (12V DC wiring kit included) Material: Premium Grade Stainless Steel Actuation Speed: Instantaneous open/close response Tech Tip: While this features a universal 51mm fitment, direct welding or slip-on clamping may be required depending on your bike's stock mid-pipe geometry. Professional installation is highly recommended to ensure a perfect, leak-free seal.
