I have a 1967 Mustang
Coupe with a 302 V8 engine and I can't decide whether to get dual glasspacks or flowmasters. I don't know much about either of the two except that flowmasters come in different series. From what I understand flowmasters are also louder and glasspacks tend to have a deeper sound. What is the difference between the two: Sound, Performance, Quality, Price, Etc. Which do you think will sound better on my stang?
