If the system, you installed, eliminates the secondary cats, then yes you will need a tune.

You will only need a tune if you have an automatic SS because it will delete the AFM valves by the rear axle.
I have a manual, installed the AWE catback w/o secondary cat delete. Same as OP. No CEL nor tune needed.
Secondary cats aren't monitored. OP most likely have a small leak right at the Catback and/or has an Automatic transmission
