PERFORMANCE KIT
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 requires an additional investment.
NEEDS TUNER
The 2011 - 2012 Touring model are required to use a tuner with our exhaust. 2010 96" Touring models can be used without but the 11's need a fuel management system to operate correctly.
NO TUNER
The team at D&D spent hours on the dyno testing the combination of a high-performance air cleaner with the BOSS Fat Cat pipe to ensure no tuner download is needed.. With just a wrench and a ratchet, every 2010 bagger owner can be up and running within an hour. That saves time and money.
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. -Dave Rash, Pope of Pipe
