Yes all California cars had turn down exhaust because of emissions.


Not even CLOSE to being true.

Noise Reduction Package, N95 I think. Same for CA Roadrunners.


In the "ballpark", but ONLY for 1970, N95 - CA emissions & N97 - noise reduction.



The '68 Parts Catalog indicates NO differences for CA vehicles & only shows one pair of Charger R/T 440 tailpipes.

The Charger R/T in BULLITT has tips & was purchased off a lot for the movie.

Nothing on your b'cast sheet is any different than another 440 auto a/c '68 Charger R/T.
