Terry,
One side runs the path of the stock exhaust system. The other side is spaced the same distance from the drive shaft - this makes is look symmetrical.
As I recall, the passenger-side pipe crosses-over under the drive shaft just behind the rear of the transmission (this had to be "fitted" to work with a 4-speed but should clear easily with a stock 3-speed).
You might want to install a heat shield on both sides (the same shield as used on stock systems).
Good luck,
Tim
