I really wanted to reply to this post a few days ago when I found it, but wasn't comfortable doing so. Speed of Sound is my company, and the gauge pillar is our first production product. We do a good bit of custom parts as well.
A procharger install on an 01 cobra vert led us to this design. We did not like any of the parts available at the time, so we made one by hand (it's the parchment one in my gallery). Made a few more on special request, then it just snowballed from there.
My part costs a little more than the others, but I can guarantee it's quality, fit, and finish surpass my competition by an enormous distance.
Thanks for the mention, it's really hard to avoid posts like this in fear of "spamming" the board I started on when I bought my stang in 02.
