At Dr. Jekill & Mr. Hyde, we are excited to announce our latest project - we have begun the development of a brand-new exhaust system exclusively tailored for the BMW R 1300 GS. Our Research & Development team is hard at work, meticulously examining every aspect of this exceptional adventure motorcycle to create an exhaust with a sound and design that perfectly complements the 1300's power, performance, and style.

To ensure that our exhaust system is nothing short of exceptional, we have embarked on an exciting journey to craft the perfect exhaust. Our goal is to fully understand the motorcycle from A to Z by testing it under various conditions and scenarios.

Your riding style might get you in trouble... your exhaust won't 'Twenty-One' for Harley-Davidson Touring Models

Introducing the latest innovation from Dr. Jekill & Mr. Hyde - a high-performance 2-1 exhaust system designed specifically for Harley-Davidson Touring models. Building upon the success of the acclaimed 'Twenty-One' exhaust for Milwaukee-Eight Softails, this new system embodies the same philosophy of sound and power.

The exhaust system offers three sound modes: Dr. Jekill mode with a closed valve for a refined sound, Dynamic Mode with a halfway open valve for a deep growl, and Mr. Hyde mode with a fully open valve for a thunderous roar. No matter the sound mode, the 'Twenty-One' exhaust guarantees a great, street legal auditory experience with a balance of performance, comfort, and excitement.
