Website seems broke at the moment, the SC1-R is quite similar to the Akra, although it looks to have a removable baffle (without having drill and piss about) which may be good for some. Pricing also seems quite competitive.
I also have the akra with baffle removed so won’t be changing anytime soon, but if they did the S1 or S1-GP in black I may consider it, I had the GP-M2 on my street triple r and it sounded bonkers.
The double underslung titanium pipes from AR are still probably my favourite at the moment, I may treat myself when spring rolls in next year.
Observation is the greatest source of wisdom.
