First thing to do is raise the radiator cap and replace that 5.4 with a PSD.... . Cut the muffler off, wait for a cold spell and when the exhaust valve closes the whole neighborhood will think a 747 landed on their street . (been there, done that).
Anyhoo, back to your dilemma. Headers and cherry bombs will make it be heard. I would suggest a Cat-back system with Flowmasters to start with. That will dent the pocketbook bad enough .
I did a little research and was considering FM 50 series SUV/TRUCK. It sounds cool at the FM site. Hasanyone heard it in person on a 5.4L? A lot of people on ford-trucks like the 40 series. does anyone have a sound file of a 40 series? My old neighbor who used to live down the street hada Durango and every morning he would start it up, andI would hear it from in my house. That's what I want.
I've heard a lot about glasspacks but don't really know what it is. I know it is a muffler but why is it called a glass pack? Are they louder than regular mufflers?
try this. its free fer starters and you get a nice sound. remove the muffler and tailpipe and let it come straight out of the catalytic converter. it has a loud deep throaty sound, especially around 4,000 rpm. idle sounds good to.

thanks
A "glass pack" is basically a perforated pipe which is wrapped with fiberglass material and stuffed inside a larger diameter tube. The ends of the outer tube are "crimped down" so the fiber-wrapped inner pipe doesn't blow out; then pipes (which will fit onto the truck's exhaust pipe) are welded onto each end of the outer tube. Their "straight-through" design increases exhaust flow and can be pretty loud.
The longer the glass-pack, the deeper the exhaust note. Unfortunately, these long 'packs also reduce the sound level. I've found that 33" makes for a nice balance between loud and deep. Of course, everyone's definition of "loud" and "deep" are going to be slightly different. I personally prefer a 36" 'pack. Not real loud, but has a very sweet note IMO.
One thing to note is that as glass-packs get older, they get louder. Basically, the heat of the exhaust breaks down the fiberglass matting and you are left with a "straight pipe" exhaust. About 12-18 months of service is all you expect from a 'pack. Good news is that they only cost about $25 each.
Honestly the 50 series will only make it sound a little louder than stock IMO. Try a 2 chamber Flowmaster with a 3" or 3.5" turndown. This setup on the 5.4L V8 should give you the sound you're looking for and its pretty cheap. Probably no more than $150 installed.

A turndown is like an exhaust tip, but instead of being straight, it bends at the end. The link below is to a picture to give you an idea of what I'm talking about. I know its of a motorcycle exhaust turndown, but I couldn't find a good one of a truck. Hope it helps:
Most people use these and attach/weld them directly to the muffler instead of having an exhaust pipe come from the muffler to the rear of the truck. You also get increased sound from a turndown right off the muffler because the exhaust echoes off the ground directly under the truck instead of echoing off of nothing out the back. Its like when you drive next to a wall with the stock exhaust that points out the rear side of the truck and it sounds louder because its echoing right off the wall. You get that affect all the time. Its cheaper than a cat back because you're only paying for a muffler and a tip instead of a muffler, exhaust pipe, and a tip. Also, any muffler shop should have these types of exhaust tips and they are chrome which makes them look nice.

I had a 2000 F-150 with a 5.4L in it prior to purchasing my superduty. I installed a 50 series delta flow flowmaster and was pretty disappointed. Not much of a difference at idle, but a little louder than stock when on the gas. I ended up adding a 3 1/2" exhaust tip, which gave it a deeper tone and made the exhaust note more noticeable at idle. Even after adding the tip I still wished I would have went with the 40 series on my F-150. I have the 40 series on my V-10, but that is like comparing apples and oranges when it comes to exhaust notes.
