You can control it. suncoast creations and others make a remote box that allow you open and close it with a push of a button. I had it on my corvette and it was a nice touch.

A lot of people on the corvette side have a shop cut it open and either exhaust clamp the pipe or weld a solid piece around it to make it a true straight through pipe. then repack it and weld it back up and you have a mean sounding car. I had the muffler mod done on my z06 exhaust and with lg headers it was loud when open but when closed it was not much louder than stock. Made cruising on the highway that much better.
I wish it was not so expensive to buy used systems because you can get used corvette z06/npp for a few hundred bucks but if you can find camaro one its like 700 used or 1300 new
