JBA Headers 1809SJS Shorty Header Stainless Steel Silver Ceramic - 1-5/8

The JBA Headers 1809SJS is a 1-5/8" primary tube shorty header crafted from durable stainless steel and finished with a polished metallic silver ceramic coating. Designed as a direct-fit replacement for the factory exhaust manifold, these Cat4Ward® headers deliver a meaningful upgrade in flow efficiency and engine output over restrictive OEM manifolds.

Featuring JBA's proprietary Firecone collector design, these headers use race-proven technology to maximize horsepower and torque gains throughout the RPM range. The mandrel-bent stainless steel primary tubes ensure optimal exhaust flow with minimal restriction, while the oversized exhaust ports accommodate cylinder head porting for enthusiasts looking to push performance further.

Key Features:

• Mandrel-bent stainless steel primary tubes — Optimized flow, improved throttle response, and long-term durability
• Proprietary JBA Firecone collector — Race-proven technology for maximum horsepower and torque gains
• Silver ceramic (metallic) coating — Increased corrosion protection and thermal barrier for lower underhood temperatures
• 3/8" thick CNC laser-cut flanges — Resists warping, prevents leaks, and simplifies installation
• Extra thick collector domes — Will not distort, ensuring a leak-free fit
• Oversized exhaust ports — Increased flow and compatible with cylinder head porting
• Factory-style emission connections — Retains OEM emission hardware connections for straightforward installation
• High-quality hardware kit included — Everything needed for a professional, no-leak installation

Emissions Compliance: This header has been granted a California Air Resources Board (CARB) Executive Order (EO) exemption — CARB EO No. D-57-33 — and is 50-state legal per the manufacturer's application guide.

Fitment Note: Header applications are based on original engine and cylinder head port centerlines. Raised port cylinder heads may cause installation issues. Installation may require modification to the exhaust system.
