1970 DUSTER 340 FACTORY EXHAUST END CUTS w/o TIPS???

In 1970 Dart swinger 340s all came with the chrome (one year only) exhaust tip and as stated above they had 1 7/8 tailpipes and the extension inlet was even smaller, EXCEPT (for reasons I can't fathom) all the California emissions cars had no tips and they ended with a kick up then down and the end was cut on an angle almost parallel with the ground like the B body pipes in post 11
