Installed on 2012 camaro ss auto. Installed great and fit like a glove. Sound is exactly what I was looking for, not obnoxiuos, but nice low deep rumble at idle and quite aggressive when hitting it pretty hard. If you have AFM, you will be disappointed and will want to disable. Going from v8 to v4 is quite pronounced compared to stock. With AFM disabled and pro series mufflers it like driving a completely different car!
