3ds Max, aligning two faces without affecting entire object?

Sorry if the title is confusing

I am modelling an APC in 3ds max and I'm trying to align the exhaust flange to the bodywork, here are some screenshots. I can provide more of needed.

As you can see I need the exhaust flange to match the angular bodywork, how can I do this accurately without rotating guesswork?

Soft Selection can do this.

To align the flange, you can use normal align on the face selection:

One other method is to detach the end>reset pivot>placement tool>attach & bridge>insert loops>set flow. But Vojtec's way is much quicker.
