Whitelightning'
A long time ago I had a '54 car and used somebody's store-bought dual side tail pipe. Then one day I had both of them down off the car and was looking at them and found the only difference was a slight turn at the front of the dual side pipe to make it point to the driver's side.
Later I needed another dual side so I just bought a stocker and propped it up on some 2x4s and jumped on it (a little-Leon cant do that "a little") just enough to get it to "point" it to the driver's side.
This way you dont have to start out with a straight joint of pipe, a zillion dollars of ells and a fresh tank of acetylene.
If you're a do it yourselfer its pretty easy. In those days we had no muffler shops in Arlington (no Rangers either) with benders. Sorry Leon-it was only a joke!
