If you want help choosing the right system or locating a dealer, our team can point you in the right direction.

Dr. Jekill & Mr. Hyde^® systems are premium exhaust systems built around engineering, materials, fit, finish, and electronically adjustable sound control.

Each system is developed specifically for the motorcycle, designed as a precise fit, and built with advanced components like the electronically controlled valve system that gives you multiple sound modes at the push of a button.

You are not just buying a muffler. You are buying a complete premium system with advanced technology, model-specific development, and a 4 year warranty.

The system uses an integrated electronically controlled valve and a handlebar switch to let the rider change sound modes while riding.

Only minimally. Most of the system’s sound comes from the damper, so the end cap has very little influence on the actual exhaust note.

End caps are primarily a design choice and can be swapped for a different look.

All Dr. Jekill & Mr. Hyde systems are made from stainless steel, but the finish still needs proper care.

• Black and satin chrome: Rinse with warm water to remove dirt and sand, then clean with warm water and a soft cloth.

Never clean the exhaust while it is hot.

It is not always obvious from the outside whether a motorcycle uses CAN bus.

The easiest way to check is to enter your bike’s model and year in the configurator.
