do i need the evap canister on my civic? im wanting to tuck and shave my engine bay and would like to get it out of there...and if it matter im not worried about emissions or anything

 

I believe your mpgs will go down, and depending on the year you will set a code, but thats obd2. So if it is older than 96 I would assume you could drive with no major issues, just would have to reline the fuel and vacuum?
