Exhaust making high pitched noise during cold start?

ibestplayer · 08-14-2022, 11:04 AM

Recently bought a 2018 340i (20k miles still under warranty) and noticed that the exhaust is making a high pitch sound during a cold start. I have a video but this forum only allows .00000000000002mb of files and I'm not figuring out how to compress it and what not. Let me know what you think.
