How do I make the truck loud???

[69C10@16]

I've got a 307 with unidentified long tube headers. 24" glasspacks right behind em and then pipe going to right in front of the back tires. It's not loud by any means at idle, but when it gets hammered, it's a beautiful sound. I wouldn't change it for the world. No, I'm not as loud as some of the other kids at school. But I'd bet a hundred bucks I could kick they're @$$3$ in a race. Especially after my uncle reset my timing and that new intake manifold got bolted on. 0-60 in 3.78 seconds. WOOOHOOO!
