Yamaha Viper Performance Header (Full Stainless Steel)
The Straightline Performance Full Stainless Steel Performance Header for all Yamaha Viper models delivers a proven 11 horsepower gain through improved exhaust flow efficiency and optimized exhaust pulse management. Featuring a true stainless steel merge collector, stainless flex connector, and premium full stainless construction, this header improves throttle response, acceleration, and overall power while providing outstanding durability and fit and finish. Even greater gains are available when combined with additional performance upgrades and tuning.
The Straightline Performance Full Stainless Steel Performance Header for all Yamaha Viper models is engineered for riders seeking maximum exhaust flow, improved turbo efficiency, and substantial horsepower gains.
Delivering a proven 11 horsepower gain, this performance header dramatically improves exhaust scavenging and engine efficiency by replacing the restrictive factory header with a precision-engineered, full stainless steel design. Riders immediately notice stronger acceleration, improved throttle response, and increased power throughout the RPM range.
At the heart of the system is a true stainless steel merge collector, designed to optimize exhaust pulse energy and improve overall exhaust flow. This allows the engine to breathe more efficiently, creating stronger power delivery and improved performance across the entire powerband.
The header also incorporates a premium stainless steel flex connector, allowing the system to accommodate thermal expansion and vibration while reducing stress on critical exhaust components. This design improves long-term durability and reliability under demanding riding conditions.
Constructed entirely from high-quality stainless steel, the header provides exceptional corrosion resistance and durability for years of use in harsh snowmobile environments. Every component is built to Straightline Performance standards with outstanding fit, finish, and ease of installation.
While the header alone delivers an impressive 11 horsepower gain, riders can achieve even greater performance when combined with Straightline Performance custom programming and performance upgrades. The improved exhaust flow allows the engine to fully utilize additional tuning potential for maximum performance gains.
Whether you’re trail riding, lake racing, drag racing, or building a high-performance Viper, the Straightline Performance Header is one of the most effective upgrades available for the Yamaha platform.
