Wow, nice gains! With cats even! Stock exhaust? Tuned? What do these babys look like? Cost? And will they be available for the LS2 GTO's just around the corner?

With cats and through Borla mufflers (made no more power on the dyno) on the one car, through cats and stock exhaust on the other car I think. No tuning because none is available for the LS2 yet.
The Kooks for the LS2 look very similar to the ones for the LS1s/LS6s.
Nice gains indeed.
