Agreed. The canister has zero effect on anything. And the SAI *can* reduce popping, but 1-a proper tune will also, so it's like putting a band aid on the real issue, and 2-unless U R running catless, it's been said disabling SAI could possibly ruin the cat because it helps to burn unburned gasses that get past the exhaust port. (gets clogged and bike runs badly) Probably not, but unless you are getting very bad popping and hate it, i'd leave the SAI alone.
you could eliminate both and it's very likely noting will change, so no real reason to do so.
