## Description

Doug Thorley Headers THY-291Y-L-C Long Tube Tri-Y Headers deliver the ultimate in performance for your 2011-14 Ford Mustang GT! Doug Thorley Headers is the originator of the tri-y header design, which is the most efficient way to increase horsepower and torque over a broad RPM range, and more importantly the range where you will use it most. That better exhaust flow produces drastic gains in horsepower and torque output. These headers are NOT LEGAL for use on pollution controlled vehicles, and are for off-road racing use only.  The headers are manufactured using heavy duty steel tubing, and super flat 3/8" thick head flanges. They are then silver ceramic coated inside and out, which looks great, drastically reduces under-hood temperatures and creates a strong barrier to protect the headers from the environment. The header kit includes a complete T304 stainless steel X-pipe kit to connect to your exhaust system.  APPLICATION SPECIFICS: 2011-14 Ford Mustang GT | 5.0L | not CARB legal.
