If i power the Arduino from a 12 V, 2.5A DC adapter, will i be able to get something like 11V from the Vin pin? I need to power my GSM SIM900A modem and i am thinking of tapping it from the Vin pin. It needs a peak 2A current when sending a SMS. Will this adapter be ideal for this?
No.
The Reverse polarity diode is only rated for 1A, you will blow the diode trying to get 2A peak from the Vin pin.
Make/buy a power splitter cable.
