The AMS tubes made a slight difference on the butt dyno (maybe placebo?), power seems to come on a bit quicker and feels like the turbos spool up quicker and a little more turbo whistle. I got in on the group buy that was going on last month and picked them up for a hair over $300 and feel they are worth it at that price.How are the turbo inlet tubes did you notice a difference, are they worth if you just have an intake? Also anyone have a video they can post of the installed exhuasts.
