Capacity of HVAC system

I did an inspection today and need some assistance on the tonage of the following system.

Goodman
S# 1101717564
M#SSX160481BA

I know the unit was manufactured 01/2011 just not sure if the capacity is 4 ton or 5 ton. Any help would be appreciated.

Never mind I found the manual online. It’s a 16 Seer 4 ton system
