I have a 2017 Hyundai Elantra (Limited, but that shouldn’t matter, right?) and I wanted to replace the rather plain looking diffuser on the back, but I didn’t want to go all out with a bumper replacement or anything. After removing the bumper clips on the underside of it, I realized it is attached on both sides. Do I have to take the bumper off to remove this thing? All I want is to replace the diffuser, I don’t need the bumper to come off if I don’t have to.
