I made an intake for my truck. I know there are concerns with homemade intakes on the newer 5.4L's (I believe 2004 and newer), and folks with more knowledge on this matter will clarify. Here is a link to where I posted (with pictures) about my homemade intake. Just for if anyone is interested.

haha this thing is great i love it how u like the performance what are u using for a filter??

 

K&N. And what's so funny??? I didn't expect a huge amount of performance. If I wanted more, real, noticeable performance I would have went with a programmer and custom tune, cat-back exhaust, headers and whatever else gives real engine performance. BUT, I don't have that kind of money to spend on that stuff. I need to replace my muffler, so I'll be getting a muffler and tailpipe from Magnaflow. Would like the full cat-back system, but can't afford it - from what I've found on the net, about $370 more.

buy ya some pipe and a muffler and weld up your own there nothing special only reason i bought mine was because im in iraq and no longer have the time to do the work

 

That has crossed my mind, since I am a bit of a do-it-yourself guy. But I think this time it will be better for me to buy either the 2.5" or 3" inlet/outlet muffler and 3" tailpipe (mandrel bent) and have a muffler shop install and weld it all together. I myself do not know how to weld. I have been told to stay with the factory 2.5" pipe into the muffler for reason's of losing some torque. Since I sometimes pull a heavy trailer (up to a full chord of firewood, which I think is heavy for my truck - I know, I need a 3/4 or 1 ton) and I need all the torque my 4.6L can produce. I'm not sure if a 1/2" difference of pipe diameter will make a difference.

well know that 2.5 will not be a deep as 3in you will not loose that much torq most people that dont dino dont see the loss its not much and keep in mine the put those other gears on are trannys for a reason

 

Nice, ive got a bit more to do on mine, but so far ive only spent 6$ not counting the filter.

Ive removed the silencer, and modded the fender inlet.

I have 3:55 gears on my truck, and I had thought briefly of putting in 3:73's (or 4:10's), but I read what the parts and labor would cost (I think close to $1200) and I quickly closed that thought. That is a job that I would want a professional to do and not myself. And for the amount of towing I do, right now, compared to the gas mileage I would get with 3:73 or 4:10's - it wouldn't be worth it. If my firewood-on-the-side-business picks up next year, I'll have to really consider a diesel 3/4 or 1 ton period.

but you do have the 5.4 mine was a 4.6 3.55 till i recently upgraded to to the tire change thats coming i used to tow livestock trailors with no probs id just dropped it in drive and i never had any probs with the power miliage really goes down though

price of regear cost around $1000 for a 4x4 about $500 for 4x2 that includes gears and install

regearing u see a huge add in power but if ur using stock tire size u will see gas miliage loss at highway

 

I have the 4.6L with 3.55's. When I bought the truck (used, 2 yrs. old) it had 255/70-16's, then I went to 245/75-16's and just recently I went to 265/75-16's. I can pull a load (cord of partially seasoned oak firewood) in Drive (3rd), but in Overdrive (4th) it keeps shifting back and forth between 3rd and 4th. So I keep it Drive and can do 60 mph at about 2300 rpm (and faster if needed). The trailer is a 18' x 83" car hauler (1960 lbs. empty) with 2' high homemade wood sides. From some internet research, a cord of oak (partially seasoned, dry), weighs approx 5500 lbs. So with a full cord on, I'm pulling about 7460 lbs. My specs for my truck say 6600 lbs max with stock setup. I added Timbren springs and Monroe Sensa-Trac load adjusting shocks and they work real good. But I probably shouldn't be doing it. Hmmmm...yep, I NEED a bigger truck. But for now, my current truck will have to do. The trips aren't very far usually and not very often with that much wood on.

Regearing is still out of the question right now. Vast majority of my truck is highway without a load, so gas mileage is important. Yes, I don't expect (and never have) car-like gas mileage.

yep time to regear you may like to go with 4.10s should free up a lot more power maybe might like a edge tunner they free up alot of power and you can adjust shift points for towing
