1 Top Rated Question

WHY WOULDN'T THIS FIT ON A REGULAR GT??

  • The Stainless Works 1-7/8 in. Long Tube Headers are designed for the 5.4L 4V engine of the GT500 and would not work on the 4.6L 3V engine found in the GT due to the differences in cylinder head exhaust ports, and engine deck height.
