I have a 1999 GMC Sierra 1500. How can I make it louder?

[Dylan]

And what is the cheapest way to make it louder? Everything on this truck is stock. Any suggestions would be helpful.

put glass packs on it or cherry bombs.

Take my advice, don't make it to loud as some cop may pull you over for excessive noise. It has happened before, not to me but have known some fellers that it happened to. He will just site you for the noise ordinance law you didn't know about.

Headers and straight pipes.

Don't run the exhaust over the back axle
