Default evap system

My question is what are the advantages to keeping the evap system? I know that it lets gas fumes into the intake manifold. I have been told it is only for emissions... If so then i can just get it tuned out and cap off the lines correct? Car doesnt pass emissions anyway so im not worred about that.
I guess my real question is will taking it out adversly affect my mileage?

There's no real reason to remove it. It just pulls the vapor off the gas tank into a canister and releases it into the intake under part throttle conditions. Doesn't affect performance at all, or measurable emissions really either. If you remove it you'd have to vent the gas tank to atmosphere and it would stink up your garage.

only advantage of removing it is for weight reduction and more room under the hood, and yes you will have to place a block-off plate on each exhaust manifold. you will set a code that can be tuned out
