HELP WANTED: I have been talking with Scott from ECS Exhaust Co.. He is willing to create full factory correct exhaust systems for '68 HEMI B bodies, but he needs to see pics of one or more original '68 HEMI muffler(s) and get the date code(s). He does have '69 HEMI B body date coded July '68 exhaust systems. His systems carry the Pentastar. I already sent him pics of an original '68 HEMI resonator (attached) , but he also needs HEMI MUFFLER date codes. My friend's HEMI resonator has a date code of 2447....the 244th day of 1967 (August). It came on an early '68 HEMI Charger (Jan '68 build date). Any help finding this info. would help me and many future resotrations!!
