I wonder if there is a cross over for some parts from the ATS 2.0T to the new CTS 2.0T, such as intake, tune, downpipe. The cat back exhaust I'm certain will not fit, but wondering on the other parts. I just made the jump to a CTS 2.0T after owning my ATS for a while, it was just too small for me, so next best thing? CTS.
