2004 GTO Kooks Headers Install

/ / Chevy SS/G8/GTO Portfolio

Impressive gains on this lovely 2004 GTO! 39rwhp & 37 ft/lbs of torque with Kooks Headers with Cats and a dyno tune. We also installed our catch can kit to keep oil from being ingested through the intake manifold. These mods make for a nice pick-me-up currently, and also lay the groundwork for future mods such as a cam or a supercharger!
