Here is a dyno graph that Nick at DT sent me of a bone stock 2008 Z06 before and after (no tune with either setup):

Look at the torque gains even as low as 1600rpm - I think with tuning you should see 40-45rwhp peak on the LS3 with no problem. Will keep you all posted on things

I'm currently running these headers + a Basanni GT Race system from West Coast Corvettes (which are actually on clearance right now) on my '06 Z06. I purchased my own high flow cats (with the O2 holes) and had them welded in by a local mufffler shop. In this setup you need to also purchase the O2 wiring extensions. Great Basanni sound + excellent HP/TQ gains. I purchased the whole system on sale/clearance - parts were $1800 complete system w/cats + mods.
