Unleash Your GT's Hidden Power.

When matched with a SW, MBRP or Corsa 3" Cat-Back you will have a full 3" exhaust system that will increase the rear wheel horsepower and torque of Coyote powered GT.

Hear and Feel the Power. These Stainless Works 1-7/8" Long Tube Headers not only improve the performance of your 5.0L V8 powered Mustang, but they will also improve its sound as well. With a cat-less high-flow design, these Long Tube Headers are less restrictive than stock allowing you to pick up a few decibels in your exhaust note for an aggressive sound you can hear and feel.

Quality T-304 Stainless Steel Construction. CNC mandrel bent, these headers are constructed from durable T-304 stainless steel tubing. Starting with 3/8" thick flanges, these Long Tube Headers feature 1-7/8" primary tubes that merge into 3" slip-fit collectors. The collectors feature a merge spike design for excellent exhaust flow. TIG-welded for superior strength, these Headers will last a lifetime.

Calibration Required. Installation of these Long Tube Headers will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your Mustangs ECU you will be able to realize the full power potential that these headers have to offer.
