Question for PA folks: Thru-the-fender exhaust legal?

Part of the problem getting pulled over by that "dumbass cop" is that now he can look for any little thing he finds wrong and to save face he probably will find something wrong. I tried last year to get a classic tag for my wife Mustang GT and because it has a rust spot on the back deck Pa would not issue a classic tag. I had to send in 35mm pictures, they wouldn't accept digital pictures printed off the computer cause they said you may have altered them..
