I just installed my AEM cai. It sounds awesome, and the car "seems" to be a bit more torquey, but that could be the illusion of the sound.

I am unhappy as to how flexible the intake is. (I cushioned impact points with closed cell insulating foam) Has anyone custom made a support bracket in their 6-speed using a cai? I have my own ideas, but I am just looking for others.

 

As far as I know no one has fabricated a support bracket to prevent it from clanging around. I took a similar route as you and packed some foam around the opening to the lower section. Doesn't really bother me now.
