The D&D Boss Fat Cat 2-into-1 exhaust system is an excellent choice for engines with performance modifications from stock to plus-25% displacement, delivering a torque curve that is high and wide, with a strong top-end pull. Excellent workmanship inside and out; broad power design really shows up on the dyno.
Harley Dyna 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, exhaust gaskets and baffles. Each exhaust system is designed and dyno tested. All 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. Upswept muffler for better ground clearance. 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.
All models are available in brilliant chrome or high-temperature black powder coat finish. Includes full-length header heat shields to ensure great looks over the long haul.
Will fit 2014-2017 Dyna Low Rider and Low Rider S with minor adjustments to the brake pedal.
