D&D's 612Z-31 Cat 2:1 Exhaust is made specifically for Harley-Davidson models listed below.
D&D all full systems are equipped with heat shields, bolt kit, brackets and baffles. This system comes with both 12mm and 18mm 02 bung's. 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. Baffle Louvered wrapped baffle only Note: The inter core of the louvered baffle is 2 1/4" All V Rod's have to be tuned with the full 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. Dave Rash, Pope of Pipe
