Superior Quality Kooks 1-3/4" Long Tube Mustang Headers

These Kooks 1-3/4" Long Tube Headers are an excellent way to increase the performance of your already powerful Mustang... adding horsepower, torque and improvements in both throttle response and fuel economy. They feature mandrel-bent primaries and over-sized exhaust ports that not only create excellent airflow but also increase power and enhance the exhaust sound in the process. The primary tubes on these headers give you perfect fitment and feature an integrated Venturi (aka merge) Collector which gets air out in a hurry by creating a pressure drop that siphons exhaust gas through the header tubes. They move exhaust so well, in fact, that your Mustang's stock computer setting must be re-calibrated in order to deal with the change in airflow.

High-Quality Kooks Header Construction & Fitment

Kooks uses heavy duty 3/8" laser-cut flanges to guarantee a tight seal. These Long Tube Headers will not fit your factory mid-pipe -- see options below. A Kooks Mid-Pipe is required for proper fitment of these headers on your Mustang. Kooks' Header Kit comes complete with quality hardware, gaskets, and instructions for a straightforward installation. They also add a great look to your engine compartment with their stylish custom Stainless Steel Finish.
