"Hi! I'm Doug. I work with twenty great guys in St. Louis at Doug Jenkins Custom Hot Rods and we're going to do some work for you today on Expert Village. Dave is using a hydraulic pipe bender in order to shape the pipes that go from the exhaust headers back to the muffler. This has to be done custom; we can't buy exhaust pipes in a box that will hold on to the performance headers and match up to the original style rear muffler and exhaust pipes. So Dave chooses different dyes that match the diameter of the pipe. So the white coated ones are for the two inch pipe. We have below, other dyes for other sizes of pipe. This pipe bender will perform a variety of functions for Dave during this custom exhaust installation. One is, to provide a bend in the pipe; the other is to expand the end of the pipe so that it will fit over other pieces."
