Yamaha 701 SuperJet Factory B Pipe Exhaust System

The Factory Pipe Exhaust system is a high-performance two-stroke exhaust system designed to optimize engine efficiency and power output. It utilizes an expansion chamber to manipulate sound waves, ensuring that exhaust gases are expelled at the right moment to maximize performance.

One of its standout features is the variable water injection system, which allows riders to fine-tune exhaust gas temperature by adjusting water injection levels. This system effectively alters the speed of sonic waves within the pipe, mimicking the effects of changing the pipe’s length without physically modifying it.

Factory Pipe’s exhaust systems are particularly popular in watercraft applications, where precise tuning can significantly enhance acceleration, torque, and overall ride quality. The tunable headpipe design enables customization based on riding style and conditions, making it a versatile choice for performance enthusiasts.
