JBA Headers 2012S 1-5/8" Cat4Ward Shorty Header 409 Stainless Steel Natural Finish

The JBA 2012S is a direct-replacement Cat4Ward shorty exhaust header engineered for the Toyota Tundra and Sequoia equipped with the 5.7L V8 engine. Constructed from 14-gauge 409 stainless steel with mandrel-bent primary tubes, this header dramatically reduces exhaust backpressure compared to the factory manifold, delivering meaningful gains in horsepower and torque while retaining full emissions compliance for all 50 states.

Key Features:

• 1-5/8" mandrel-bent stainless steel primary tubes — smooth bends maximize exhaust flow and improve throttle response
• Proprietary JBA Firecone collector — race-proven design optimized for peak horsepower and torque gains
• 3/8" thick CNC laser-cut machined flanges — resists warping, prevents leaks, and simplifies installation
• Extra-thick collector domes — won't distort under heat cycles like thinner competitive headers
• Oversized exhaust ports — increased flow and compatibility with cylinder head porting
• Factory-style emission connections — retains original catalytic converter and stock gaskets for a clean, compliant install
• 2.50" collector outlet — compatible with stock mid-pipe, no additional exhaust modifications required
• Natural stainless finish — optional silver metallic ceramic or titanium ceramic coatings available separately
• CARB EO Exempt (D-57-33) — 50-state emissions legal
• Includes high-quality mounting hardware and installation instructions

Installation is straightforward with an estimated time of approximately 7 hours, making this an ideal bolt-on upgrade for enthusiasts looking to unlock more performance from the proven 5.7L i-Force V8. The JBA 2012S is backed by JBA's performance guarantee and one-year manufacturer's warranty against defects in materials and workmanship.
