Fits 2009-2016 Harley FLH/FLT Touring Models with S&S T143 Motors Only
The D&D 625Z-31T Mega Cat 2-into-1 exhaust in black delivers aggressive performance and bold style for 2009-2016 Harley FLH and FLT Touring models running the S&S T143 motor.
⚠️ This system fits S&S T143 engines only.
D&D engineered the Mega Cat with a stepped header and a 4 1/2″ muffler body to maximize torque, horsepower, and throttle response across the RPM range.
The stepped header increases in size starting at:
-
2″
-
2 1/8″
-
2 1/4″
-
2 1/2″ (where the muffler meets the header)
This progressive step design improves exhaust velocity and scavenging, helping your big-inch Touring bike produce stronger mid-range power and a deep, aggressive exhaust tone.
The 625Z-31T Mega Cat Black features:
-
Straight cut muffler
-
No end cap included
-
Optional interchangeable end caps available in the dropdown menu

Durable black finish for a clean, aggressive look
If you run an S&S T143, this Mega Cat system delivers the flow, sound, and performance your build demands.
