Vance and Hines made this so easy to install, even an amateur can do it. It took longer to program the modes(values even supplied by V&H website) than it did to actually install and route the product. I am very pleased to add this along with V&H big radius 2 into 2 and the V&H VO2 air intake setup. Took a total of about 3 hours to install all 3 products from start to finish. The sound is amazing, even better at half to W.O.T. Totally worth the price and the turning of peoples heads as they hear you roar past them!!!
