Default Gasket between exhaust manifold and turbo? Not needed

I ended up not using a gasket between manifold and turbo. I used a very thin layer of red rtv high heat gasketmaker but there was no gasket there earlier.
The TD version of the Greenbook (d24T owners manual) mentions "no gasket necessary"
Then a good d24t forumer also texted me not to stress about it. Thank you

The red rtv worked very well above the turbo piping, between the upper tube's flat surface and the intake manifold itself. I used some on the threads of 2 of 3 bolts too because 2 of them reach all the way into the inside space of my intake manifold, and those two bolts used to let oil out via the threads (i guess).

Finally the car runs without the exhaust leak sounds, builds noce pressures, very responsive, sounds great runs very well and pulls very hard, smokes much less, nearly nothing when pedal gets floored. Turbo is smooth and constant at "every" rpm. BTW it spools quicker and earlier too.
The EGR delete was a great idea. Looks ugly for now bc I had to fabricate them very quick due to freezing weather.

Updates soon...
