I have the QTPs with turndowns and wireless remote, had them on just about a year now. Are you looking for pics of where they're at on the exhaust? After I had them put on the exhaust(between long tube headers and mid muffler), I wrapped the wiring in heat-protective tape and routed it up through the shifter boot in the center console. I think I went behind some heat shielding too somewhere? From what I recall, there were 4 bolts to remove from under the car and then just the trim around the center console. I just used the 12v outlet inside the console armrest for power, and tucked the remote receiver in there too. It's all hidden nicely.
I didn't have a lot of room for the muffler shop to install these where I wanted without reducing my ground clearance there some, that's my only gripe with them. This thread was very helpful for me with everything start to finish.

If you guys want, I could get underneath the car sometime soon for some pictures of the wiring.
