Kooks LS3 Header Dyno Test & Install

Kooks Custom Headers offers a trick headers and X-pipe setup which would allow us to use a real 3-inch exhaust “Z06” style, but not necked down to 2.5-inches like the original Z06. They did, and this is the story. We then capped off our installation on our Corvette with a Corsa 3-inch exhaust.
