Default Cold Start click when accelerating

Alright so I just got my 2006 sti a couple days ago and everything is going great. It seems to be running perfect, hitting target boost, etc. It is all 100 percent stock and will remain that way until I have some money for a downpipe and tune (already have my exhaust.) My question is, when I go out in the morning and start my car, I generally let it warm up for about 5 minutes. When I start driving, I can hear a very very quiet ticking noise. Its definitely not a knock and is not loud whatsoever. It can only be heard when the stereo is completely off. It happens when I accelerate usually through 1st and 2nd gear. Like I said, it is super quiet to the point of barely even being noticeable. I talked to a couple people who all said it was probably just my lifters/typical boxer engine. It only occurs when the car is warming up. After driving for about 15 minutes, it can no longer be hear for the rest of the day. What do you guys think this could be?

It's normal, I believe it's the injectors pulsing.

Perfectly fine, nothing to worry about. Most subarus do this on warm up and is nothing to be concerned about
