Yeah removing the AC system will make your car 38lbs lighter . Someone on here posted a DIY thread on removing is AC system and the weight on it was 38LBS . At the time I did'nt think him posting that would help any but hey here we are ! . Umm yeah if your the nice straight person go get the system dumped by someone who has a tank . If not just let it out into the air the world is F**cked up enough as it is you know !
