I don't feel that it's too restrictive.
If you are looking for ultimate HP, than yes, a 2-1 can be restrictive over a 2-2. Compared to a stock silencer setup, I feel an aftermarket 2-1 flows better than 2 stock silencers. For our trail use I only see maybe 1-2 HP loss at max RPM, but torque gained in the low end that is more helpful.
The carbon is less strong compared to stainless or titanium bodies for continuous pulses. I have also had several Aluminum bodied silencers of other brands fail b/c of this too.
You'll get more flow removing the quiet core, We have seen a 3-4 hp gain by removing that with proper jetting. I need the spark arrestor for our riding regulations in our area, so that stays in for us.
