1 Our virgin 2012 Dyna Fat Bob is ready for modifications.. HB Staff Visits Vance & Hines for a Behind the Scenes Installation of the Big Shot Staggered Exhaust, Fuel Pak, and VO2 Skullcap Crown Since 1979, in the drag racing world no other names like Terry Vance and Byron Hines has stood for winning, quality, and performance. After teaming up at the drag strip the duo started building racing exhaust for their bikes and eventually moved on to creating applications for street bikes. In the late ’80s they expanded their straight-line performance into road racing and even ran an AMA factory team for Yamaha. During that time, the company made huge advances in motorcycle exhaust technology including the race-inspired Big Radius 2-into-1 pipes as well as others. With the integration of fuel injection several years ago, V&H has gone digital with its own propriety fuel management built 100 percent in-house at its Santa Fe Springs, California, facility. In fact, all of the Vance & Hines production is made entirely in the 100,000-plus square-foot factory. With more than 400 employees, the entire operation runs like a world-class orchestra with each department playing its part. 2 The stock exhaust is big, chrome, and way too quiet.. 3 All exhausts start off as long single pieces of pipes.. 4 This is what is left after the brackets are punched out of flat sheets of steel.. 5 The huge pipes are cut down depending on final exhaust size.. 6 After being bent in a computer-controlled bender, a technician checks the pipes on a jig to ensure proper size. 6 After being bent in a computer-controlled bender, a technician checks the pipes on a jig 4 This is what is left after the brackets are punched out of flat sheets of steel.. 8-9 Pipes are assembled with both human and computer controlled welders.. 8-9 Pipes are assembled with both human and computer controlled welders..
