You're more or less on point with this. However, there are a couple things that stand out for me.
1. SC makes some great exhaust systems for MotoGP teams. This tells me they generally know what they are doing or the top teams in the world wouldn't trust them at all.
2. I honestly feel like the the Akra, while very nice to look at by maintaining the lines of the original design, is just that. Nice to look at. It may very well provide some gains from stock, but just about anything else with CATs removed would do roughly the same.
3. My two biggest issues with the Akra are the price and overall reliability. And with the reliability where it is, I can't justify the price. I was just about to pull the trigger on one, but after having held TWO different broken headers in my own hands and hearing of countless others, I just won't do it.
Honestly, at the end of the day, titanium just doesn't cost that much. Sure there is a good amount of R&D that goes into the cost, but again, they have sooo much experience producing exhaust systems and it's not like they are starting from scratch, so it doesn't really justify the cost.
Sadly, these bikes are a dime a dozen these days (of course when I can finally get one, everyone has one), so the volume is measurable and there isn't really a reason for the large surcharge, other than it's a Ducati and people will pay it.
