I have used them in the past for my '07 Cobalt 2.0 SS/SC with great success, and now they offer this.
I would check them out as ZZPerformance has been doing a lot of R&D on the ATS 2.0T.
ZZPerformance ATS
'14 ATS 2.0T w/ 11,738 miles and already has issues.
1) AC smells moldy and mildewy after using the AC then letting the car sit (apparently there is now a service bulletin to address/fix this).
2) Car chimes at random while driving.
3) Microphone for the hands free makes extremely audible noise...
