Underground TRD ORP Build with mods parts list & prices

[Fredot]

Seriously - best bang for the buck was the dynamat sound deadening . Makes a world of difference! When you shut the doors, it sounds like a BMW/Mercedes. When you turn the stereo on, it sounds like a concert hall. Here’s the link:

Amazon Basics Sound Deadening Mat, 18" x 32", 9-Piece

This was enough material to do all 4 doors, rear hatch, front floor, rear floor ( not including hybrid battery area). IMO, the roof/headliner area is not necessary, and would require extra material.

How did you install? Pics?

How bad was the turbo whine? Every once and a while i can hear a little turbo whine on mine... Brings back memories of my 5.9 Cummins... i dont mind the whine.

Finally done! (except maybe an OTT Tune). Included a list of part numbers and sources if your planning the same mods. Did everything myself - so no labor costs. I originally had a SXTH element CAI installed as part of this build. After driving for 10 minutes I realized there’s no way in hell my wife would ever ride in the truck with me. It was way too noisy. Constant turbo whining will annoy just about anyone. I put in the K&N performance filter, and life is good…with a tiny bit more gro

any reason why you didnt go a full 2” on the levelling kit ?

thanks

Thanks for providing so much detail and this link! I’ve been toying with adding sound deadening to my ORP but am a little intimidated by the idea. Currently weighing the cost of pre-cut SoundSkin material vs your share — did you just cut small sections as you went to get the coverage desired? Also having limited trim removal experience (myself, that is), curious if you were able to save all your plastic clips or if you had some spares on hand prior to the tear down?
