I purchased my first T/A challenger in 1979. I proceeded to the CT DMV for registration and inspection where the car flunked due to the factory side exhaust. I showed the DMV guy the factory repair manual and explained the car came that way when new. He explained to me that in CT the exhaust had to exit behind the rear bumper and that he funks cars like mine and C2 corvettes with factory side pipes regularly. I went home, swapped the exhaust off my other challenger, passed inspection and put it all back. 13 years later Dodge introduced the viper and got CT to change the law so my T/A was finally legal after 22 years! Gotta love the states.
