The valve serves as the heart of Dr. Jekill & Mr. Hyde®'s exhaust system, rendering it truly unique with three electronically adjustable positions. Striving for the ultimate riding experience, the valve must consistently function optimally in every situation, and this is achieved through the use of a robust solid valve.

Milled from a single block of pure solid metal, their valve ensures stability by preventing deformation and absorbing vibrations, resulting in a superior and more resonant product. The valve housing features a double layer with a ball joint to minimize resistance during the heating phase while riding.

Solid Valve for your custom Exhaust

Dr. Jekill & Mr. Hyde® stands out as the sole exhaust manufacturer with a fully sealed valve. The chemically nickel-plated valve permeates the steel's pores, enhancing hardening and protecting against corrosion. Positioned in the middle and welded, the valve allows exhaust gases to bypass, achieving the optimal configuration for sound, performance, and emission without being visible from the outside—a seamless fit with their clean aesthetic.


Each Dr. Jekill & Mr. Hyde® exhaust system incorporates premium absorption fabric positioned just below the body sleeve. Utilizing heat-resistant glass wool capable of withstanding temperatures up to 800 degrees, they employ a single thread construction rather than loose fibers, ensuring an optimal lifespan.

To secure the thread in place, a temperature blanket—similar to the one used by NASA for the space shuttle—is employed. This blanket effectively prevents the transfer of temperature to the body, preventing any discoloration.

The absorption fabric plays a crucial role in providing effective damping for Dr. Jekill & Mr. Hyde® exhausts. Filtering out high and mid tones from the exhaust sound, it contributes to the distinctive character and optimal emission values associated with Dr. Jekill & Mr. Hyde® systems.
