Conflict NMAC
Flight Crew Took Evasive Action
Human Factors
I was cleared for takeoff and fly runway heading out of the class delta airspace of ZZZ. Their radar was out of service so all departing aircraft were cleared to depart runway heading until exiting the class delta. I was cleared after a twin piper got cleared the same way. The piper started deviating south south west out of the class delta. I reached the same altitude and once outside the class delta noticed the piper suddenly turn left towards me [at] roughly the same altitude. I descended to avoid the aircraft and turned away. My collision avoidance system warned me multiple times about the traffic conflict once the other aircraft turned towards me.Going forward in the same situation I will maintain a slower speed so that I will remain behind the slower aircraft until I have a clearer picture of their intention.This also highlights that this situation is far more tricky than flying out of an uncontrolled field where aircraft continuously communicate their intentions.
