That is not a cable, it is a piece of 1/4 threaded rod that you carefully bend a half inch at a time. yes I said a half inch at a time in a vice slightly opened wider than the rod. Once you got the rod bent to the 4" dia of the PVC pipe you put rubber hose around it. It takes a little patience but as you seen if you take your time it turns out really nice. I bent both of these in like 5min. Just ask Butch I am master at bending this stuff. If you take your time it will fit exactly and snug around the PVC. Just remember to leave enough straight to fit through your mounting bracket. As far as a K&N part number don't know, both Butch's and mine are Spectre and can be purchased at any O'Rieley or Auto Zone stores. They do make several different colors and styles these are the biggest and they do have several rubber rings in them to fit smaller pipe if you want but 4" is the largest it fits.
As far as do these things work, flat out YES. I have had Spectre on 2 vehicles now and notice better fuel mileage and HP in both. Seemed to help my 99 Dodge Ram more though. None the less they are fun to build and sound crazy. Have fun building them..
One more thing I would suggest is to dry assemble all the part and mark with a sharpie at all the joints to line them up when gluing. Puller out glue it and paint... Be sure to send some photo's of any improvements to the design.
Hope I answered all your questions.
