Description
Upgrade your 2007–2010 Ford Mustang Shelby GT500 with the Stainless Works Long Tube Headers, engineered for performance, durability, and a deep, aggressive exhaust tone. Featuring 1-7/8" mandrel-bent primaries, 3" high-flow catted lead pipes, and a 3" X-pipe, this system is built to deliver noticeable gains in horsepower, torque, and throttle response—whether you’re running a stock 5.4L or a modified setup.
Crafted from 304 stainless steel and TIG welded for strength and longevity, these headers feature oval exhaust ports that precisely match the factory cylinder heads for a secure, leak-free fit. The 3" slip-fit collectors include merge spikes to improve exhaust scavenging and reduce turbulence for smoother flow and increased performance.
The Factory Connect design allows for seamless integration with the OEM exhaust system or Stainless Works cat-back exhausts, providing flexibility for future upgrades. With a balanced X-pipe layout and high-flow catalytic converters, this system enhances exhaust tone while maintaining drivability and emissions compliance (not California legal).
