If i get a full akro system, does that mean i can go to stage 2 on my tune?

Yes, some tuners even have an akra evo specific tune (stage 2)

Yes, that's what I did. Alex at Alpinemss has a Stg 2 Akra specific tune for the 100 cell race cats.

I think the Akra Evo with cats/resonators sounds incredible on YT, but I've never heard in person. How does the volume and smell compare to stock + primary bypass pipes?

Volume is a touch more than stock in-cabin but not but much, especially after cold start. My wife is happy to ride in the car w/ me so that should say it all. The Smell...in-car or in traffic, not noticeable at all. For anyone behind or next to you...it does smell a bit but not terrible, aka like catless.
