I agree the headers look cool, and they are very, very long tubes which means they also replace your stock cats with some type of higher flow units. I did talk to an LG rep yesterday about their units, which will run close to $2k prior to installation. LG claims that their cat replacements should pass emissions tests. I always ask this because with the imminent use of "smog dogs" in many areas of the country, most of us will need to stay emissions legal all of the time.
To-date, they have no before/after dyno information for the effect of their headers on a basically stock Z06. The person i talked to indicated that they would be glad to this type of test once you bought the units - they will test them before and after they install them for you. I do not know what they are charging for installs.
Hopefully some of these questions will be answered once a few folks opt to go this route....
