Here is an illustration that might help. Even though the illustration shows that the 440 applications had tailpipes not resonators we have had customers claim that their original 71 6barrel/pak 440 cars were equipped with them. Like always "never say never with Mopar". Maybe for some extra cash one could get resonators as no modifications are required for installation.




Could it have been 'required noise reduction' like in 1970 for CA sold cars?
