Well, I've had the F-150 for three months now. Here are the modifications that I've done. Overall, I'm pretty happy with it.
  • Short antenna
  • Chrome XLT fender vent
  • Bed rocker panel caps
  • Roll up Tono cover
  • Dee Zee bed mat
  • UPR catch can
  • Replaced center work surface console.
  • MBRP cat back exhaust
  • 2" MotoFab front level kit
  • Removed rear 1-5/16 blocks
  • Kenda Klever R/T's 35 x 10.5 R17's
  • Front end alignment
Things to Do:
  • Alcantara steering wheel
  • Floor matts
  • Re calibrate speedo for 35" tires
  • Trans pan with drain plug
  • Remote trans dip stick

I think your truck looks great but I might be a bit biased. Mods are listed in my signature.

WOW !! look at that shopping list you put together !!!

How does it go with the 4:11's ? How does the Hypertech Speedo correction module work ?
With the 35's my speedo is off 3-5 mph.

Thanks.

4.11s and 35s bring the overall gears back to within 1-2% of stock as it came from the factory. It still rips and will spin the 35s if I’m not careful.

But the speedo was still a solid 10%-12% off so I used the Hypertech module as recommended by a friend.

The module works well but you need to pull your dash apart and plug it in to a box behind the center 12” screen/stereo/head unit. Not really difficult and I had done that before with my stereo/amp upgrade. Use a laptop to set tire size. Took me two tries but now my speedo is dead on to my GPS.

Most will say just use Forscan but I’ve read too many posts where guys did something in Forscan and it messed other stuff up. I don’t trust myself to get the coding correct.

Love what you've done to it! I have the EXACT same truck without the mods (so far).
So question #1, what cat back system did you use? Loud or mellow?
#2, Did removing the blocks cause any pinion angle issues?

#1, I went with the MBRP, street version. Straight out the back. I have the MBRP system in my Mustang GT with the -H- pipe. It's a perfect mellow tone. I did swap out the 4-1/2" exhaust tips for 3" tips. This reduced the slight megaphone tone. #2, I drove the truck home from the dealer, 2 hrs on the highway. I pulled the rear spacers out that afternoon. I haven't had any issues or vibration.

As a cheaper and quieter alternative to cat back systems, I spotted this product available at Walmart online of all places. It's just a Y pipe exiting the stock muffler, splitting into 2 tail pipes.
The product description says it fits ALL wheelbases F-150 2021-2025 with a single exhaust.
I've not seen this before. I assume it would be almost as quiet as the stock exhaust but, with a couple of chrome tips, give the truck a sportier appearance. Since it's behind the stock muffler, any sound would probably be unaffected by the CD system.
Have any of you guys or gals seen these or had any experience with them?
It's sold by

This kit is about $200.
