D&D 619Z-31 Stubby Cat 2-Into-1 Black Exhaust
Fits 2009-2016 Harley-Davidson FLH / FLT Touring Models
If you want stronger mid-range power and an aggressive tone, then the D&D 619Z-31 Stubby Cat 2-into-1 Black Exhaust delivers. Not only does it feature D&D’s new Vortex Louvered Wrapped Baffle, but it also improves exhaust flow thanks to its stepped header design.
Specifically designed for 2009-2016 Harley-Davidson FLH and FLT Touring motorcycles, this system works exceptionally well on 96” motors and larger. As a result, riders experience improved throttle response and stronger pull through the RPM range.
Features & Performance Benefits
-
First, the stepped header design improves scavenging and increases torque.
-
Additionally, the head pipes transition from 1 5/8″ → 1 3/4″ → 1 7/8″ → 2 1/4″ at the muffler inlet for optimized flow.
-
Moreover, D&D ceramic coats the headers inside and out to control heat and increase durability.
-
While the exterior features a black ceramic finish, the interior uses silver ceramic that appears white.
-
Furthermore, the system includes both 12mm and 18mm O2 bungs, so it integrates easily with autotune systems like ThunderMax.
-
In addition, the new 2” Vortex louvered wrapped inter-core baffle enhances sound while maintaining performance.
-
Finally, the rotatable end cap lets you fine-tune the visual stance of your bike.
Fitment Information
-
Fits: 2009-2016 Harley-Davidson FLH / FLT Touring

However, this system does NOT fit 1990-2008 models.
D&D designed the Stubby Cat specifically for stretched bags. Therefore, when paired correctly, riders should not experience ground clearance issues.
if you install this exhaust with stock bags and ride aggressively, you may contact the muffler end. Consequently, damage caused by improper bag setup is not covered under warranty.
