Electronically adjustable exhausts for BMW GS series

The Jekill & Hyde Company, a leader in electronically adjustable exhaust systems, has expanded its product range to include the BMW Boxer models (in addition to Suzuki, Honda, Harley, Victory and Indian models).

The company says that "performance, design and sound were the focus of the development of the new system", and that there are two different designs to choose from - black or carbon look. The stainless steel slip-on mufflers are mounted on the original mounting points on the original manifold.
The rider has three different legal sound modes available, selectable using a handlebar-mounted switch - all 100% legal and EC/CH-tested.

The Travelling mode is quieter than the original, but maintains stock performance; the "dynamic" mode, with the valve open to 50%, is similar to the BMW exhaust system, but with a deeper sound and improved performance. In the Sport mode, with the valve wide open, the engine develops an increased performance and produces a deep and earthy Boxer sound.
The company says that their system is lighter than stock and that power gains of up to five percent can be gained in the Sport mode.
Fitments for the GS series are the first to be released, but a model-specific application for the R nineT will also be available soon.
