Welcome aboard. Looks like you've done your home work and here's my 2cents for what its worth.
The 4 into 1 is the best exhaust from everything I've read in terms of weight, heat reduction and power. Weight being the bigger of the three. I have the 4 into 2 and love it.
If your planning on useing the stock luggage though verify it'll work together. Some dont.
Great sprocket choice and with the mid range on this bike it works really well together.
Ivan's tune for the 15 was actually tested and perfected on his personal Ninja 1000. Not a Z1000. For me it made as near to perfect what I was concerned with (throttle) as could be. The power increase in tune combined with the exhaust isn't anything the brag about but its felt for sure. Contact him on the ecm. Supper nice guy and very helpful, I did the same thing and still ln have my stock controller with OEM tune he found for me. Seriously you should call him.
No clue on the notorious or turbo but bet this bike would respond well to it and look forward to reading about your adventure. Good luck.
