you wouldn't want to do that to a stock mustang much less anything else. Key is having the right backpressure, if you ran a cutout back by the axle it would be ok, enough backpressure, it would just sound like a redneck pickup truck with glasspacks. There is a balance when running open headers, depending on the engine it can increase your torque and a little rwhp, on some stock engines it can cause the opposite effect (open headers) and a cutout in the right area could increase your tq/rwhp a little.
Here is my racecar, 396 stroker, open headers.

What you need is a properly tuned exhaust that uses the sound waves to create scavanging. Also, you want an exhaust system that keeps the exhaust temps as high as possible. Hot air = light air and light air is easier to evacuate from the tail pipe. That is why so many high performance engines use have wrapped exhaust all the way to the muffler.

Actually backpressure is bad for performance. A good exhaust system will minimize backpressure as much as possible.
