Bagger motorcycles
D&D Slip-on Exhaust mufflers only.
All Slip-on systems are equipped with
Heat shields,bolt kit and baffles.


The BOSS 548-11/12 slip-on mufflers are designed

exclusively for the 2009-2014 Harley-Davidson

touring models. These mufflers straighten out

the stock pipe that comes slanted-in from the factory.

Each exhaust system is designed and dyno tested
in our facilities.
Every pipe is designed to increase low-end torque
and horsepower.
Performance increases are about 3 to 5 percent
with stock headers and there is no tuning need
on a stock motor with high flow air cleaner.


Louvered and

Louvered Wrapped baffles


Note: The inter core of the louvered baffle is 1 3/4"


Increase your performance by adding a
Zipper's HiFlow Air Cleaner.
The D&D exhaust system with a Zipper's air cleaner
is the biggest bang for your buck.


Note: Zipper's air cleaner does not come with
the exhaust system requires an additional investment.


Note: Will not work on the 2010 Street Glide or

Road Glide with factory 2:1 system.


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.
