D&D 647-11T Black 4″ Mufflers for 2017 & Newer Harley Touring
Upgrade your 2017 and newer Harley-Davidson Touring with the D&D 647-11T 4-inch black slip-on mufflers and give your Milwaukee-Eight engine the sound and performance it deserves.
Factory exhaust systems restrict airflow and mute the true character of your bike. D&D engineered the 647-11T slip-ons to increase exhaust flow and deliver stronger performance. As airflow improves, throttle response becomes quicker and acceleration feels more responsive. At the same time, your Touring produces a deeper, more aggressive exhaust note.
Instead of a soft factory tone, you hear a bold, boomy rumble that commands attention without overwhelming long-distance rides. The result is a clean, powerful sound that matches the strength of your Milwaukee-Eight motor.
The 4-inch black finish adds a stealthy, performance-driven look to the rear of your bike. The larger diameter enhances your Touring’s stance, while the durable black coating delivers long-lasting style and corrosion resistance.
These slip-ons fit directly onto 2017 and newer Harley Touring models, so installation stays simple and straightforward.
