Do you have to keep the charcoal canister?

[LaunchHard]

Doing an engine swap and trying to get rid of everything that doesn't have to be there. I believe it's called the charcoal canister (sits directly underneath the battery on a 1g). I asked Mo, and he said he had it untiil he got his AEM, but was unsure if I could get rid of it. I have a stock ecu with a safc2. Any info helps. Thanks.
