Zackman, I think fixkick has answered your questions already.
fixkick said the mufflers you referred to, are [offset on the rear]. This means the inlet exhaust pipe is centered going into the muffler; the outlet is offset to one side, so this tells you the muffler is intended to be installed in one direction. (IE. directional=Yes; reversible = No)
The 2 mufflers you compared have very different prices because the more expensive Walker 47715 is made of stainless steel, and the cheaper optional Walker 18217 is made of aluminized steel.
The existing muffler on your car is probably not one of these 2 Walker products, so the existing pipes etc. are not going to work with the Walker mufflers without adapters.
Published pipe dimensions are sometimes misleading, since you need to consider inside and outside diameters of pipes, as these vary with pipe metal thickness. (I.D. and O.D.)
