On a bone stock car there isn't much of a performance difference, but the Signature system is a little deeper sounding and includes valve control.

On a tuned, high output car, the stock rear muffler becomes more restrictive and that's where the performance gain of the Signature system becomes measurable over the midpipe + stock muffler.
