Hi. I just purchased a very nice, original 1966: Aqua Mist, Matching deluxe bucket/console interior, 69K miles. Car is great! However, it currently has GlassPack mufflers, which are a bit loud. I have a 1971 Boat Tail GS which has MagnaFlow exhaust, which provides a nice rumble but is more "civilized". The 1971 has a 455, the 1966 has a 425 - so I am not sure I can predict that the 1966 will sound similar to the 1971.
My question is this: has anyone installed Magna Flow mufflers on the 425 engine? Before I spend the money I am trying to figure out what it will sound like. I am not interested in going back to stock exhaust with resonators and mufflers and giving up the muscle sound completely!
All opinions welcome! Thanks.
