JBA Headers 1675SJS Mid-Length Shorty Exhaust Headers 1-5/8" Silver Ceramic Coated

The JBA Headers 1675SJS are precision-engineered mid-length shorty exhaust headers designed for the 2005–2010 Ford Mustang GT equipped with the 4.6L 3-valve modular engine. Manufactured from high-quality stainless steel and finished with a silver ceramic coating, these headers provide superior heat resistance, corrosion protection, and a clean underhood appearance.

JBA's mandrel-bent tubing technology ensures smooth, unrestricted exhaust flow from each cylinder, reducing back pressure and unlocking hidden horsepower and torque across the RPM range. The 1-5/8" primary tube diameter is purpose-matched to the 4.6L 3V engine's power characteristics, delivering optimized scavenging and improved throttle response compared to restrictive OEM manifolds.

Key Features:

• 1-5/8" primary tube diameter for optimized exhaust flow
• Silver ceramic coating for heat management and corrosion resistance
• Mandrel-bent stainless steel construction for durability and smooth flow
• Mid-length shorty design for straightforward installation with minimal modification
• Designed to work with factory O2 sensor locations
• CARB/emissions compliance — check local regulations for street use
• Includes all necessary gaskets and hardware for installation

JBA Headers are manufactured in the USA and backed by the company's limited lifetime warranty. The 1675SJS is a proven performance upgrade for Mustang GT owners seeking real, measurable gains in exhaust note, horsepower, and torque without sacrificing reliability or fitment quality.
