Straight Devil Exhaust System for Harley Davidson Sportster Models
More Sound. More Style. Fully Street Legal.
Rediscover your Harley Davidson Sportster with the MILLER Straight Devil - the high-performance complete exhaust system made from premium stainless steel.
The term “Straight” refers to an aligned header design, where the pipes run parallel without any offset. This not only creates a unique look but also improves the overall line flow of the bike.
Each header features a cover plate over the pipe, providing a clean, refined appearance and effective heat protection. Your motorcycle will look powerful and stay technically top-notch.
With Euro 3 / 4 approval and an engraved certification number on the mufflers, the Straihgt Devil exhaust system is, of course, 100% street legal – suitable for all Harley-Davidson Sportster models from 2004 to 2021.
Technical Highlights
✅ Increased Power: +1.8 HP
✅ Higher Torque: +2.1 Nm
✅ Weight Reduction: –1.6 kg
Your Style. Your End Cap.
Choose from three interchangeable end caps to match your bike and your personal style.
The Straight Devil exhaust system is available in heat-resistant matte black coating - built for durability and a striking appearance.
Install. Start. Enjoy.
