Q: Do the fuel-injected models require adjustments with your exhaust? A: Yes and we offer Fuelpak for effortless fuel management that you can do yourself. Vance & Hines recommends the use of a fuel management system for all fuel injected applications.
Q: Why do mufflers blue? A: Mufflers can discolor for any number of reasons; not rejetting can cause discoloration, or too rich or too lean a jetting may also cause it. Small diameter mufflers can also discolor due to the heat generated by their size.
Q: Do your pipes come with exhaust gaskets? A: No, you will need to contact your local dealer.
Q: What is your best performing pipe? A: The Pro Pipe HS and Power Chambered exhaust systems are our best performing exhaust systems for Softails, Dynas, Sportsters and Dressers.
Q: What is the horsepower and torque gain with your exhaust? A: Generally, on a stock V-Twin, installing our complete systems and an air filter system is good for a 10 ft/lbs torque and 10 hp increase.
Q: Will your pipes work with the baffles removed? A: We do not recommend the removal of the baffles due to the large loss in torque and midrange you will experience. – less–ZoomInfo
