the resonator in 7th gens is a huge box thats connected on both sides by plastic tubing (guides the air into the actual filter). i think it has a total of 3 pieces that are tightly clipped and/or bolted together. when all pieces are fully assembled, it forms this "V" shape w/ the resonator box at the bottom point. its impossible to take out by trying to pull straight up from the engine bay, mostly b/c its bolted onto the cars frame inside the fender somewhere. get to it by removing the front bumper.
