Summit Racing has different size stainless steel butterfly valves you can install on a second muffler outlet or exhaust pipe to turn it on or off or anywhere in between.
They are opened and closed by a stepper motor and you have a remote switch inside the car to open the butterfly or close it.

If I had your muffler I'd be tempted to cut the other exhaust pipe off at the muffler and install one of these and weld the pipe back on so you could control the volume and backpressure from a switch inside the car.
