Sealing an exhaust

So I popped my hood today, and found this HUGE leak between the flanges on my aftermarket 4-2-1 stainless header. It seems that the flanges are warped. I dont have time to take it into a shop, so I was wondering what ways i can seal this leak>?

I was using high temp gasket copper sealant, which then turned brittle and cracked. Right now i wraped the flanges really tight with this header wrap that i had. This seems a little better, but still leaks

Anybody have any luck with this exhaust sealing stuff? I was thinking about wraping the flanges with some sort of metal tape, probably about 15 layers, and then wrapping it with the header wrap, maybe 5 layers of that, and then using some sort of wire to keep it tight, does this sound logical?

The leak is where the 4 runners meet the 2 runners, that flange, its warped.

Take it to a muffler shop and have them weld it, it will take like 10 minutes and hold a lot better than anything else.

I heard the welds will unweld if you dont seal up the flange with a gasket.
