So I understand that these mag tube extensions are legal, but honestly I’d really like it explained how they are legal. I thought there was an exemption from the 5 round limit for non detachable magazines but turns out I was mistaken.

Someone feel free to correct me, but I believe the technicality is that pump actions don't have mag limits and they are likely categorized as sold for those models, and these just HAPPEN to also fit some semi auto models.
I bought a nova mag tube extension, that happens to fit the m2 as well 🤷

That's not technically correct. The mag tube is a single component of the complete magazine. When assembled the complete magazine must not be over capacity for the type of firearm it's assembled on. The complete magazine on the shotgun is somewhat fuzzy since it's a mechanical system built into the action.
This means when assembled the magazine cannot accept more than 5 shells of the type the shotgun was designed for, eg 3" or 3.5". The tube alone is irrelevant what firearm and caliber it was made for.

Okay, so if a tube extension I own would fit on my semi auto and make it illegal, is it illegal if it’s just sat in a box somewhere not attached to anything?

It's just a tube until you build it into a mag. On its own, it's not a mag, but rather a component of one.

Correct. Manual action rifles/shotguns of any kind (pump, bolt, lever etc) have no mag limit.
The “loophole” with a semi auto shotgun is that the 5 round limit is for the largest shell it can fire. So one with a 3.5” chamber that will hold a maximum of 5 rounds of 3.5” will also fit 7-8 rounds of 2.75”, and remain completely legal.

No, the one in OP is specifically for a semi and doesn't fit on pumps.

M4 ships with 4 round 3" (aka 5 rounds of 2.75") tubes.
It is legal to extend it to fit 5 rounds of 3" (or 6 rounds of 2.75", as a result).

That's why the Stoeger is a great gun for IPSC. It's chambered for a 3.5" shell.
Add a tube to give you 5.5 rounds of 3.5 and jam it full of 2.75. I think it holds 8 in that configuration.1

It depends of how you scale it Most people don't use there guns much , and manufacturers know this. It's like a gym membership, the whole gym industry is bast on 40% of the members not turning up.
If you are a 1000 rd a year kind of person your better Turkish shotguns may last a few years The cheaper once may not last a,week of its a,semi auto
If your a 500 rds month or more you are not going to be happy.
The mew panzer arms, canuck operater elite now the new Federation arms All the same gun , have made some big improvements . This issue is they are toys. If you use them for defense or for competition I would consider buying usxmadexor Italian. Or just be realistic with you expectations

Turkey guns are for people who dont intend to buy guns for their kids/grandkids to have one day.

Panzer Arms is a stupid name for a company.
