Lastly, along with the 10% volume increase, I'd say there has also been a 10% increase in a more metallic rasp sound. Noticeable mainly during start up and the first few minutes driving.
Burbles are more raw/crackly now and also 10% louder.
Overall I am happy with the switch but again, I want to give it a few days before writing something more concrete down.

Overall, yes you notice a difference between res and non res with an aftermarket exhaust also paired.
I'm close to ordering this exact setup. Would it be fair to say that the new efficient mode sounds like the old sport and new sport and sport plus taking it to another step up?
No. I wouldn't say efficient is like old sport mode. It's less aggressive still due to the valves being closed. You can have valves open in efficient mode. That's more similar to old sport minus the burples.
New sport/sport+ do go up a level though.
