Exhaust Header Manifold for Toyota Land Cruiser FJ40/FJ45/FJ55/FJ60 (1969-1987)

Maximize Flow and Power for Your Toyota Land Cruiser 4.2L

Who Is This For? This is built for the dedicated Land Cruiser enthusiast owning an FJ40, FJ45, FJ55, or FJ60. If you are restoring a classic 2F engine or looking to improve the breathing of your off-road rig, this 6-into-1 header is designed for your build.

The Factory Bottleneck: The original cast-iron manifolds are notorious for being heavy, restrictive, and prone to hairline fractures after decades of heat cycles. This restriction traps heat and limits the exhaust scavenging your inline-six needs to perform at its best.

The Engineering Solution: Our 6-1 piping design uses precision-bent 1.50" x 1.25" primary tubes to streamline exhaust gas velocity. Constructed with CNC-machined 7/16" head flanges and high-strength TIG/MIG welds, this header ensures a flat, leak-free seal. The 3-stage polished finish provides a clean look under the hood while replacing brittle OEM components with durable stainless steel.

The Comparative Edge

• Performance Scavenging: 6-into-1 collector design improves torque and throttle response compared to stock logs.
• Industrial Build: Features a thick 7/16" head flange and 3/8" outlet flange to resist warping under high temperatures.
• OEM Replacement: Direct replacement for OEM part numbers 17100-61082 and 17111-61020.
• Professional Finish: 3-stage polish for superior corrosion resistance and engine bay aesthetics.
