Product description

From their entry into the motorcycle market in 1955 Yamaha have grown to be one of the big four motorcycle manufacturers in Japan. During the 70’s they won the first of many 500cc world championships and have maintained that success through to the modern era of Moto GP. During the 80’s Yamaha introduced the EXUP, a new exhaust system for 4-stroke engines that included a power valve which optimized the width of an engines powerband. The first of their YZF models the R1 was released in 1998 and shortly followed by the R6 in 1999 and since then they have gone from strength to strength especially with the introduction of their MT range in recent years. Scorpion have a long history of producing performance exhausts for numerous Yamaha models over the years and have supported many teams in top flight racing.

Full System:

Scorpion’s expert technicians have developed a high-performance full system specifically for the Yamaha YZF R7 Euro 5+ (2026-current) models. Here’s a closer look at the specifications and available options!

What are the advantages of a full system? Scorpion offers full systems in cases where individual slip-on and/or headers options are not feasible. These systems are sold as complete packages, allowing you to enjoy the full benefits of a performance exhaust system. This includes a high-flow silencer, unrestricted de-cat pipework, and race headers.

Once installed, performance is unlocked by enabling exhaust gases to flow more freely. The high-flow silencer design and integrated de-cat pipe eliminate highly restrictive emission filters that muffle exhaust tone, create excessive back pressure, and limit tuning potential. Additionally, the improved headers feature smooth, gradual bends that help each cylinder efficiently expel exhaust gases.

The result? Increased power capacity, vastly sharper throttle response, significant weight reduction, and dramatically improved sound. These systems represent Scorpion’s ultimate “full firepower” option.

Lastly, Scorpion’s M12 Lambda Catalyst prevents the engine management light from activating, preserving ride mode select functionality. It spaces the lambda probe from the exhaust flow, filtering remaining gases to trick the ECU into detecting a functional catalytic converter. (For motorsport use only.)

Silencer Styles:

Serket Taper: Delivers sleek, aerodynamic aesthetics paired with a refined, performance-inspired exhaust note, elevating your riding experience.

Red Power: Designed with a shorter, retro-inspired compact appearance, it delivers a bold, guttural soundtrack that amplifies your bike’s personality.

Silencer Finishes:
