Perforated Wrapped baffles are for Stage 4 103" to 113" motors
Note: The inter core of the louvered baffle is 2 1/4"

Will not fit the 2013-2017 Breakout Softail because
the top vent line touches heat shield.

 


 

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.
