Hope you paid via credit card, cause this you can always dispute.
If you are worried about the gap between the two flanges it's not really an issue, that's a ball and socket style joint, so the flanges don't actually need to touch to seal. It doesn't use a gasket.
I'm not trying to defend the work, but I can see what happened. You are trying to mate an aftermarket part to a corroded, oem part that relies on a tight fit between the two surfaces (and not gasket) to seal. Because the aftermarket stuff is probably crap and the OEM part that is on there does not have a smooth surface, he probably had a hard time initially getting the spring bolts on there without it leaking. It would appear that he figured out a way the 2nd time around, but it still leaks, again probably because the surface isn't pristine or the ball and socket don't mate perfectly (because one is crap aftermarket and one is old OEM).

Rationalize? here goes...
Customer brings in non-oem "guarunteed" to fit midpipe for crusty old jalopy and is looking for the cheapest place in town to perform work. R&R whizbangery no problem. Get car in air, see iron oxide factory and whip out cutting torch to remove old parts. Install "guarunteed" to fit aftermarket midpipe only to find it fits like isht. Install gaskets, new generic fasteners, and some exhaust paste to git R dun. Fire it up, doesn't sound like a freight train, ship it, flag 2 hours and head over to the urgent care for a tetanus booster.
Does that make it right? Not at all.
Individual results may vary.
The grey **** is likely a non Permatex branded gasket maker. Iíve had good luck using the Permatex stuff but itís copper colored.

Tracked Porsches (Cayman/964) have all leaked, even my Infiniti header to cat gaskets leaked.
Only solutions i've ever found not to leak are actual metal gaskets.
It also should be noted that I rev the **** out of all of those vehicles (high EGTs).
Bottom line you didn't realize this product existed, and we're talking crap like you were a know it all.
I stopped using gaskets on turbo installs almost 20 years ago.. stopped having leaks.
Part of the problem is once half a gasket blows out the flange is not evenly torqued and it warps. Once it warps unless you machine it flat it will never evenly clamp down on the gasket and it will blow out again and again.
Not necessarily a solution to the round woven or compressed donut style but I try to never install flat gaskets on new flanges and they have less problems.
also I know what it looks like in there, and that is not what it looks like...
should look like this without the gasket...
fact is this: they sourced the midpipe, the gaskets, I brought in nothing. They used the wrong gaskets and hardware and tried to seal the incorrect gasket with exhaust putty. It leaks from the flange. It sounds like ****.
(make sure to unmute as there is audio)
listen for the hissing sound...

No, my concern is primarily that exhaust is pouring out of that flange and it sounds awful. Secondly that they used incorrect hardware, incorrect gaskets and tried to seal it with putty... I wouldn't REALLY care if it looked like this and wasn't leaking.. but alas... it is definitely leaking out of that flange... rear one is solid but looks horrible.
here is the new OEM gasket btw...

Bottom line is that I do know what Iím talking about, and I do know difference between a flange joint and a slip joint that uses a donut. My point was trying to explain that the silver stuff was probably not regular gasket maker but made to seal exhaust leaks. Then I mentioned that Iíve had success with the copper stuff in reference to another person saying they only use metal gaskets. It had literally nothing to do with the OPs car but tell me again how the copper stuff I posted isnít for exhaust.

If one needs some schmoo to seal up exhaust, Ultra Copper is one of the best options available. It's just high-temp RTV but works well for flat flanges against a flat surface.
Most Toyota joints use the aforementioned donut gaskets, which work well on stock applications. But the hack job exhaust that this thread is about no longer resembles anything close to stock Toyota.
OP - take your car to a good performance exhaust shop, not the cheapest place available, and have them fix this mess. Unfortunately this will end up being a lesson that the cheapest shop will provide you crap work 99.9% of the time.
