Default How to make 7.3 louder?

I have a 91 7.3 (mechanical) f250. I have dual 5 inch straight pipes on it and want to make it louder than it currently is. Any ideas?

get rid of the 5 inch pipe and run 3 inch. the smaller pipe reverberates more causeing a louder cackle.

You get a crackle sound at higher rpm with smaller pipes as apposed to the lazy rumble of bigger pipes.
