I appreciate your effort and dedication to do this at home but a muffler shop could have made a proper tail pipe (using your tip) for less than what you paid at Canadian Tire.
The tube of cement's instruction state how to use it as structural connector... But I admit the stuff may not be strong enough.

But I may end ups having to get it welded one day. Dunno, will see. But all the material is already cut and bend... So it would be only a few weld here and there on the joint pipe.

I understand what you mean but what the label sais and what it actually does under twisting/load is another story. Once the cements is cured it becomes very rigid. Since this is the end of the exhaust, there is little mass left that can twist the joint apart but just to be safe keep an eye on it for the first few weeks.

You might try a stainless steel band clamp to hold it on. They are flat and about 3" wide and they stretch a little when you tighten them. I use them on big truck exhaust all the time and they come in a variety of sizes. They are real strong too

Ok... Muffler cement holds 2 weeks.

It still hold between clean new part. But between new and old part, no luck. Didn't hold.

So I went to "Silencieux Proteau", a really nice place which only do exhaust and stuff. They have that great "fast food" way to do thing.

80$, and now I have a clean thing, welded and it holds and works great.
They used my tips, but they flushed all the piping and clamp I did.

So... If you want to do exhaust, get yourself a MIG.
