Try VW for a start as they might be cheaper than you think, you also need the tensioners.
I will add and don't take this the wrong way but are you aware of how much work is involved in replacing them.
No not at this hour lol. Yeah I want fall kit not just the chains.
Do I know? dude I ain't happy about this! But would rather pay for them to be change than pay for a rebuild.
Should you hear the chains at all though? It's fine at idle, sounds sweet. I only ever hear them when on light throttle. can't hear them with load on the engine, hard throttle, off throttle. Just cruising.
