Quality Construction. Kooks Long Tube Exhaust headers are manufactured from 1-7/8" mandrel bent 304 stainless steel tubing for superior airflow. These headers are TIG welded and feature a leak-free ball flange design for optimal performance and a better than OEM fit.
Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a custom tune with either a SCT SF3 or SCT LiveWire Custom Tuner.
Application. These Kooks Long Tube Headers are designed to fit the 2011-2014 5.0L GT Mustangs. Kooks long tube headers require the use of a Kooks shorty midpipe in order to be installed properly (see drop down option above).
