1995-2005 Harley Dyna Fat Cat

2:1 Fat Cat is a stepped header system
at the head is 1 3/4" to 1 7/8" at collector
and 2 1/2" where the muffler goes to the header.

All full systems are equipped with heat shields,
bolt kit, brackets and baffles.
Best exhaust gaskets to use SE gaskets from Harley
Each exhaust system is designed and dyno tested in our facilities.

All of our testing is done with Harley SE Tuner.
Every pipe is designed to increase
low-end torque and horsepower.
Performance increases are about 8 to 10 percent
with the proper tune on the bike.

Louvered baffles are for 80" to Stock 103" motors
Perforated Wrapped baffles are for Stage 4 103" to 113" motors
Note: The inter core of the Louvered baffle is 2 1/4"
Note: The inter core of the Perforated Wrapped baffle is 2 1/2"
525-31-32 does have 18mm 02Bungs in the header pipe
All Dyna's have to be tuned with the full system.

Note: Using Woods cams for best performance use Perforated Wrapped Baffle.

At idle, the motorbike is deep, boomy
and full of character. Not only does the pipe look good,
it is a wonderfully sounding experience for the rider.
