I don't kno if the truck finally got used to the cats being on and teh o2's but it's running awesome, even with the 35's!!! Wish i could have gotten it runnin like this before i took the normal tires off, just to see what she'd do! lol Tires way like twice as much and i can break them loose pretty easily, i could barly make my little tires bark before the LT's! lol
I have a video on my cell phone but it wasn't running like it is now, but ll try and post it up anyway

i think PI was late 99 for 5.4's and early 01 for 4.6's i think.
but a set of 99-03 5.4 PI heads will fit on your 4.6. both have the same heads i have 5.4 heads on my 4.6 block factory. get an aftermarket cam's and ive heard people talk abotu getting 50-110 HP from a PI swap.
the o2 bung looks awesome. glad they worked out for ya.

I'd prolly just use the stock pi cams bc cams aren't cheap! But who knows! i think id have to get a custom tune done too

Nah, you won't get as much HP as you think from a PI swap. Probably around the same as you do from LT headers. A PI swap IMO wouldn't be worth it unless you had a blower to go with. Then you would have something. Collecting all that can add up to quite a bit. Set back and think about it, - why not just purchase a used 5.4L SVT (Lightning) engine that's already built from the ground up, -factory.

Lol, Actually i left them an alright review bc these headers would prolly bolt right up on your truck no problems. They just werent meant for my truck exactly...I mean they did say 99-03 5.4. oh well, i got them on now.

Sounds good! Goes pretty good with 35's. Sounds a little different then mine, maybe it's just the muffler.

Thanks! it does, i didn't think i would like no muffler but it actually a pretty good sound imo, it not overpowering!(loudness)
Yours seems alot quicker, but my speedo is also way off! Prolly when it says im doing 67-70 im really doing about 80 bc tires. I'll get a vid on my phone here in a sec before work. lol
Nice videos btw!
