JBA Headers 1618SJS Stainless Steel Silver Ceramic Shorty Exhaust Header 3.7L V6

The JBA 1618SJS is a stainless steel shorty exhaust header finished in a silver ceramic coating, engineered as a direct replacement for the restrictive factory exhaust manifolds on the 3.7L V6 Mustang. JBA shorty headers are significantly less restrictive than stock manifolds, dramatically increasing the power and efficiency of the engine while retaining factory-style emissions connections for a straightforward installation.

At the heart of the 1618SJS design is JBA's proprietary Firecone collector, a race-proven technology engineered to maximize horsepower and torque gains. Primary tubes are mandrel-bent for optimal exhaust flow and improved throttle response, while the 3/8" thick machined flanges resist warping and ensure a leak-free seal. Extra-thick collector domes add further durability and prevent the distortion common in lesser-quality headers.

Key Features:

• 1-5/8" diameter mandrel-bent stainless steel primary tubes for maximum flow and durability
• Proprietary JBA Firecone collector — race-proven technology for maximum hp/tq gains
• 3/8" thick machined flanges — resist warping and prevent leaks
• Extra-thick collector domes — eliminate distortion and leaks found in lesser headers
• Oversized exhaust ports — increased flow, compatible with ported cylinder heads
• Factory-style emission connections — simplifies installation and maintains emissions compliance
• Silver ceramic coating — heat-resistant finish for long-term durability and appearance
• Includes high-quality hardware and installation instructions for a professional no-leak fit
• CARB EO Number D-57-48 — emissions legal in California and CARB-compliant states

Each JBA shorty header system ships complete with all necessary hardware and detailed instructions, making this one of the most effective bolt-on performance upgrades available for the 3.7L V6 Mustang.
