Headers ALOT louder??

Would putting shorty headers and dual exhaust on my 76' 350 nova make it nouns a lot louder to the point where on earth it would be hard to enjoy a convo in my sports car while on the freeway? My dad keeps describing me that its going to be too loud with headers on, is he merely trying to scare me or is it true? Right presently my car isnt "very" loud, I expect you can hear it coming but it has a nice "bom bom bom" nouns, but I want headers so it will perform better.

What type of fuel should I use...

Its not the headers that breed noise, its the mufflers or withdrawal of that follow them. Headers are notorious for leak and require constant maintenance, compared to pattern iron manifolds. Although if you re-jet your fuel system to match you may gain a small increase within gas mileage to go beside some extra horse power.

I hold really low MPG on my...

dual exhaust is sufficient

no need for headers on a stock motor

alter your differential to a 3.73
