Length of Tail Pipe Efficiency

Just wondering, all else equal, is there any efficiency difference between a long tail pipe (say from exhaust manifold to rear bumper) and a short tail pipe (say from exhaust manifold to right behind the front wheel)? I know the circumference of the pipe will make a difference, but will the length?
