I've got an 06 Malibu 3.5 v6 and I can't seem to get any help on any of the Malibu forums... for those of you that read the thread a few days ago, I am jwakamud'* friend and I finally decided to register.
Does anybody have any experience with any of these? The Injen is supposed to be "tuned" to maximize performance, but I don't know if that really makes a difference, perhaps I will research a little more later, didn't find anything on first look. Also, if I go with the Injen does anybody think it is worth pulling off the bumper to put it behind? And does anybody know how hard it is to take off the bumper?
