D&D Fat Cat Chrome 2-into-1 Exhaust – 579Z-32F
Fits 1984–2017 Harley-Davidson® Softail Models
If you want classic chrome styling and serious performance, the D&D Fat Cat delivers both. Unlike basic slip-ons, this true 2-into-1 system improves exhaust scavenging; as a result, you get stronger throttle response and usable low-to-mid range torque.
Moreover, the high-polish chrome finish gives your Softail a timeless, show-quality look. Not only does it boost performance, but it also complements both stock and custom builds.
Why Riders Choose the Fat Cat Chrome:
-
True 2-into-1 collector design for improved exhaust flow
-
Stronger low- and mid-range torque where you actually ride
-
Deep, aggressive D&D exhaust tone
-
High-polish chrome finish for classic styling
-
Made in the USA for proven quality
In addition, when paired with proper tuning, you can expect smoother power delivery and quicker acceleration. Therefore, tuning is recommended after installation to maximize performance gains.
