hey there,
ok, i am only 16 and dont got alot of money, lets establish that. Now to what this is all about, I have a 87 f150 with the 4.9L in it. Me and my friend put some custom duals on it, I put a glasspack on it and stayed with the 2 1/4" pipes, and split it into duals after the rear end..it looks nice, i got some nice tips on it. But its not very loud, i also had a flowmaster on there for like a day..that wasnt very loud either. Is there anything I can do to make it louder, or is the 4.9 not meant to be loud. Thanks for any comments or suggestions.

Here is a cheap method to making your truck louder. Just take off the muffler and weld in pipe in its place.
