I think the Stillen kit numbers are fine IF you do a custom tune after install. There seems to be a lot of good reviews on the GTM kit (stage I) but delivery seems to be the main problem...people seem to have to wait for months. At this time if you decide on stage II, you'd still be an early adopter...you may have to deal with some of the associated growing pains as kinks get ironed out.
