Shared chassis is always a great thing because I was able to choose rear sway bars from TSX, TL, and TLX. OEM means more economical and more accessible as well.
The final decision was to go with the 25.4mm from the TLX v6 and the part number is 52300-TZ3-A51 and bushings (x2) 52306-TZ3-A01. Factory endlinks and bushing brackets can be reused.
This setup greatly neutralizes the vehicle and does induce oversteer at hard turns, allowing for more dynamic driving compared to factory's understeer biased configuration.
I do not have pics of the installed product but the following is a picture of it waiting to be installed.
