Have a 2007 Fatboy, I am changing the stock exhaust with Vance and Hines True duals and have had many different answeres from people about having the computer remapped or retuned for the fuel / air mixture. now I am going to do this eventually when the finances allow. but is it a must to do or can i ride the new exhaust in the time being. Thanks
 
I put V&H long shots on my 05 hertiage (fuelInjected) Do I need a fuel pak or anyother turner ?
