Never heard of them... You do realize that an 04 GTO has the same engine (LS1) as a 2002 Trans Am right? So if they worked on the TA then they will work on your GTO. Not saying they will work well but they will bolt on.

Check the setup (cam/headers) that the guy with the TA had, if it worked well for him and meets your target numbers then just duplicate it on your GTO.
