Here is my intercooler. First I added 2 iron angle pieces to support the intercooler and added 2 big nuts and washers to have some extra space but later I removed nuts and washers and placed intercooler directly on top of the angles. I had to do this because of the front grill.
The intercooler connections are 2.5" but my aluminum piping is 2". I used pipe stretching tool and tig welder to fix this.... Pipe stretching tool is super handy I always use it for exhaust etc applications. It works even with stainless pipes.

Here is my exhaust pipe. I used 2.5" 304 stainless pipe from eBay.
Exhaust flex. I added another one before second elbow from turbo later as I could still feel some engine vibrations. Originally there was not even 1 flex and the whole truck was shaking, now it is so much better.
I decided not to go over the rear end and used small resonator.
I wasn't sure about noise but as it came out there is less noise and almost no vibrations compare to the original exhaust system. It is really amazing how turbocharger "eats" all the exhaust noise.

The oil return line.... I was reading and thinking and reading again and thinking again, but at the end I decided that the bigger oil return line the better and took oil pan off and just welded a piece of tube big enough. Also I had a chance to clean it all up. The biggest challenge for me was to find RTV as all parts stores were closed because of COID... I actually had to call somebody and ask him to open the store for me and sell it....
I build my own oil return adapter for turbo side:

Now probably the best part... turbo itself...
I bought HOLSET HE221W 3782369 3782376 CUMMINS Turbocharger 6.5 CM. The exhaust side on this turbos can be 5 CM or bigger one 6.5 CM.
I paid $ 265 for it and I think it was a good deal for a genuine Holset turbo. I decided to go with this one as it is not too big and I am not after BIG POWER. I made a few changes. First I had to clock it to have oil return straight down. Because of this I had to drill 2 extra holes for turbo actuator. It wasn't a big deal as the aluminum body is thick enough and I just drilled extra holes with no problems at all. Secondly I welded a piece of aluminum tube to discharge side as it was made for flange connection.
Here you can see turbo clocked and turbo actuator relocated:
