What are the possible benefits of having dual exhaust on my 77 F150 trailer special?

 

There are several benefits from this. But it depends on your driving habits.

1. Cool sound, those 400s sound good with one out each side
2. If you pull anything with it, it will help a little
3. I personally like the looks of dual exhaust
4. Dont we all want just a little more power?

Its not necessary, but if you have to replace what youve got, now is the time to upgrade.
