Default How to make my straight pipe louder

I recently just straight pipe with a 4 inch stainless steel tip on my 5.4l 2002 fx4 f-150! It sounds good right now ,but my #7 coil pack is bad and my truck is still misfiring after I fix that I want to make my straight pipe louder ! What can I do to make it idle louder and just overall be louder haha!

My brother has a 2010 fx4 f150 and has the same setup and his sounds so much better but I think it's cause his type has more valves idk

Anything helps first time doing this I know I'm a noob to the forum world

Sell your truck and buy a v10 or diesel?

In actuallity:
Remove your cats. After that you don't have much else to do.

I have to ask...what is the obsession with a trying to get as loud as possible? At a demolition derby it's fine but on your daily driver? It pisses me off hearing that obnoxious loudness...

this is just an idea i had in mind.. after your cats up the pipe size to 4" or 4 1/2" piping and in theory this should make your truck louder.. and here is why.. so if you shout through PVC piping the small normal PVC piping you use in sprinkler systems you get a sound right but it not very loud... but if you shout through a big pipe than it echos. so i would think if you up the pipe size it would echo the sound and be louder. now how much bigger do you have to go i would think maybe 4 1/2" or maybe 4". now i have not tried this but always thought about it. if anyone has other thoughts on this please share
