Weird "tweak" when starting the engine

[Kacper]

Hi guys,
it will be hard to explain but since a few weeks I hear a weird "tweak" noise when starting the engine. Except of the noise everything is fine but I was wondering if anyone experienced anything similar with your ST? It is kind of metalic noise when starting the engine and then everything is okay - it begun like 4 weeks ago, beforehand I did not hear the noise.
My ST is 2013, mapped 212 HP, 353 NM.
Best,
Kacper

Mine was doing that and it was an exhaust heat shield. If you can get the car up on a lift or jackstands, tap the head shields along the exhaust and listen for "buzzing" or a ringing sound.
