I am running an axel back off an 07' STI. It like it, under 2k it has a nice low rumble and just hums nicely on the highway without being a obnoxious or flashy.
This was great, the concert before hand was excellent and these were by far the best fireworks that I have ever seen!

Yeah, this is very convenient, and the way I mounted them if you hit something (I.e. snowback getting into driveway) the mounts just push to one side or the other so you can just push them back without screwing up the mounts or anything.
1.) As for the length, I would have to measure them. I cut the 48inch piece in half and drilled the first hole in the back and then mounted that to the car, and held the light up to where I wanted it and marked for the second hole and left about an inch in front of the hole as not to weaking...
