..you have to be kidding..lol
Went out this morning after ordering the remaining gaskets/bits bobs fully expecting to hear that noise, only worse as now cold..but..
Probably best you listen..
First video from cold (ignore oil level light as faulty)

After 5 minute drive (summer here, so reaches temp quickly)

A little way through (24 secs) you can hear a bearing noise, aware of this, either w/pump or alternator (possibly).
The down pipes although stainless are a lot less meaty than those removed, this doesn't help but the noise is barely audible.
