07 335i 107k miles rattle noise

Need some help boys. new to this forum platform.
wondering if anyone has any clue to why my n54 has a rattling noise. rattling happened after catless dp. rattles on start up, rev and when accelerating. I'm at 107k miles so its possibly those pesky wastegates but I've seen others last way longer and this vehicle was well maintained by the previous owner. Any ideas on what to look for or what to test to get to the bottom of this.
