Has anyone installed this with a test pipe yet? I don't have to pass emissions tests (KS) and I figured might as well do it all at once.

If you still have the stock header with the stock catalytic converter (upstream) the sound does not change much I have it that way and I still pass emissions here in TX (by the way I do not have a CAI so I don't know if how much louder is with a CAI and test pipe). I have seen and heard other more expensive systems and this is by far the best bang for the buck if you want a good sounding exhaust vs plain loud.
