YMS V8 Raw Steel Performance Exhaust

Transform your 2-stroke’s powerband with the YMS V8 Yamaha Jog Performance Exhaust. Specifically engineered for 70cc to 100cc Big Bore builds, this high-flow system is designed to maximize exhaust scavenging and top-end RPMs. Featuring a “Raw” industrial finish with a protective clear coat, the V8 provides an aggressive racing aesthetic and a deep, crisp exhaust note that defines the Minarelli tuning scene.

Technical Performance Features

• Engineered for Big Bore Kits: Tuned expansion chamber geometry specifically designed to complement 70cc-100cc cylinders for significant gains in mid-range torque.
• 24mm High-Flow Header: Features a 24mm inner diameter to reduce backpressure, allowing your 2-stroke engine to breathe freely at peak RPMs.
• Raw Steel Aesthetic: Finished in raw steel with a high-temp clear coat, showing off the precision welds for a custom “garage-built” racing look.
• Precision Taiwanese Manufacturing: Crafted by YMS in Taiwan, ensuring superior fitment and weld integrity compared to generic performance pipes.

Mechanic’s Note: The YMS V8 is a legendary “Street-Pipe” because it stays relatively quiet at idle but screams when you hit the powerband.

Installation Tip: Because this is a raw steel pipe with a clear coat, avoid touching the header with bare hands during the first heat cycle to prevent oil spots from etching into the finish.

Pro Tip: To truly unlock this pipe, ensure you are running Lighter Roller Weights to keep the engine in the V8’s higher powerband!
