ZZP Catted Downpipe - 400 cell cat. I had it in my ATS for ~ 2years so there is some surface discoloration you usually get with stainless. Took it off when I sold the car. Bolts on any ATS/CTS/Camaro with the LTG. $240 shipped.
E39A ECM - It has a base ZZP tune for 93 octane on 2013 ATS. I don't think it can be used unless it gets wiped for a new VIN but if you need a spare or want to peek at their tune with your Tuner Pro? $80 shipped
