I recently purchased a 66 Charger with the 383HP engine. The muffler system appears fairly new and correct with the cross over pipe between the exhaust pipes. They have a good sound at idle and on acceleration but they have a loud drone sound at highway speeds. I had a new 63 Plymouth 383 and a new 67 Plymouth 440HP in the 60's and they did not have the drone. So I'm asking what would be a good sounding stock muffler for these cars. I cannot live with the drone but need to know what to tell a muffler shop about replacement. Any info would be appreciated.
