What would be a good temporary exhaust system?
I have my wife drive it down there while I'm at work... when she did that with my 69 barracuda, she almost jumped through the roof when it fired... I told her it would be loud but.... she didn't realize how loud.... (LOL) they also happened to be doing construction on the road in front of our house... they guys got a kick out of her driving it out with open headers.....
Oh yeah, if you are by a cop, try to keep your foot steady so you are not accelerating or decelerating a bunch... decelerating a bunch can make a bunch of noise too!
