Rebel, I thought the 04+ intakes had an external silencer. If not, though, and they're the same as mine,
HERE is a write up on one way to do it.
I did not remove the flexible portion as suggested in the write-up, and, after tearing mine out, realized it may be possible to remove it in one piece, without using the Dremel. It looked to me as I started, like the pieces were glued or molded together. Once out, though, it was obvious they are not. The silencer "snaps" into a groove in the main body. If one could get a screwdriver between the pieces and pry, they might be able grab it with some needle-nose pliers, and work it out. After cutting mine all the way round with the Dremel, though, the "ring" bent up and came out with pliers, and the rest of it followed pretty easily without mangulation.
