I am sure there are perfectly legitimate reasons to have one of those in your truck besides bragging rights.
I checked again and it is saying $652 - 877 for an HX. I do not remember it asking which submodel before.
CX, DX, and LX:
EX: $621 to 847
EX: $640 to 865
GX: $661 to 816
Si:
: $782 to 1003
The cheaper models do not have EGR. The Si is more complicated. The GX is natural gas, so it makes sense that it could cost more, I just find it curious that it also might be cheaper.
Apparently when I looked it up before I just searched for what I put in the title and I found:

For a 2005 it says $1,076 - 1,358 and does not ask for submodels.
For a 2010
it says $1,433 - 2,053 and asks for submodels.
For a 2010
it says $1,003 - 2,024 and asks for engines.
For a 2018
it says $1,722 - 2,147 and does not ask for submodels.
