D&D 654Z-31T Billet Cat 2-Into-1 Black Exhaust

Fits 2023 & Newer Harley-Davidson® CVO Touring Models

If you want real performance from your 2023 & newer Harley-Davidson® CVO Touring, then a properly engineered 2-into-1 exhaust is essential. The D&D 654Z-31T is specifically designed for the Milwaukee-Eight 121 engine; therefore, it delivers stronger torque, improved throttle response, and measurable horsepower gains.

Unlike factory dual systems, a true 2-into-1 design improves exhaust scavenging. As a result, your CVO pulls harder through the mid-range and maintains power under touring load.

• Increased low-end torque

• Stronger mid-range acceleration

• Improved throttle response

• Increased overall horsepower

• Deeper, aggressive touring tone

• Better performance when carrying passenger or gear

Furthermore, this system supports both stock and performance builds, making it ideal for cam upgrades and custom tuning.

System Features

• Precision billet collector design

• High-flow catalytic configuration

• Durable black finish

• O2 sensor bungs for factory or wideband tuning

• Compatible with ThunderMax®, Dynojet®, and dyno tuning

Because tuning matters, pairing this exhaust with proper fuel management maximizes both rideability and power output.

In short, if you’re serious about unlocking the full potential of your Milwaukee-Eight 121, the D&D 654Z-31T 2-into-1 exhaust delivers the torque curve and sound CVO riders expect.
