When maximum airflow is the goal, compromise isn’t an option.

That’s why we partnered directly with Kooks Headers to develop a true 2″ Primary x 3″ Collector Long Tube Header specifically for the Pontiac G8 enthusiasts looking to push their combinations beyond the limits of traditional header designs.

Unlike standard long tube headers, these feature massive 2-inch primary tubes feeding into a full 3-inch collector, providing the airflow needed to support serious naturally aspirated combinations while truly shining in high-horsepower boosted applications.

Whether you’re running a cam, a centrifugal supercharger or a positive displacement blower, these headers provide the flow capacity needed to support substantial horsepower gains without becoming a restriction as power levels increase.

Built entirely from premium 304 stainless steel, these headers are manufactured by Kooks in the USA and deliver the fitment, craftsmanship, and durability that have made Kooks one of the most respected names in performance exhaust systems.

One of the biggest advantages of this package is flexibility. These headers are designed to bolt directly to a Kooks X-Pipe, making them a perfect upgrade for existing Kooks-equipped vehicles. They are also compatible with many popular Kooks-style exhaust systems including configurations from manufacturers such as SOLO Performance and CORSA that utilize Kooks-style connections.

Most importantly, these headers are a G8Only exclusive. While Kooks manufactures numerous header options, this exact 2″ x 3″ combination was developed specifically for our customers and is not available directly from Kooks or through other retailers.

If your goal is maximizing airflow, supporting future power upgrades, and investing in a premium exhaust system built to handle virtually anything you throw at it, these are the headers you’ve been looking for.
