Exhaust Manifold Header for Toyota 4Runner & Pickup (1984-1989) 2.2L 2.4L

Optimize Exhaust Scavenging for Toyota 4Runner & Pickup 2.2L-2.4L Engines

Who Is This For? This performance header is purpose-built for the Toyota enthusiast maintaining or restoring a classic 22R or 22RE engine. Specifically designed for 5-speed manual owners, it’s the ideal solution for those seeking better throttle response and a more durable alternative to aging factory parts.

The Restrictive Factory Bottleneck: After decades of heat cycles, original cast-iron manifolds often develop hairline cracks or warp, leading to exhaust leaks and lost power. These heavy stock units stifle the 2.4L engine's ability to breathe, especially when climbing hills or navigating off-road trails.

The Engineering Solution: Crafted from high-grade stainless steel, this 4-1 header design maximizes airflow by accelerating exhaust gas velocity. The CNC-machined 7/16" head flanges provide a thick, stable mating surface to prevent future leaks, while the TIG and MIG welded construction ensures structural integrity. With 1.50" primary tubes and a 2.50" outlet, this kit facilitates a smoother exit for spent gases, resulting in noticeable gains in mid-range torque.

The Comparative Edge

• High-quality Stainless Steel construction offers superior rust resistance compared to OEM cast iron.
• Precision CNC-machined flanges (7/16" head, 3/8" outlet) ensure a perfectly flat sealing surface.
• Full 4-1 piping architecture improves engine efficiency and provides a deeper exhaust note.
• Complete installation package includes downpipe, gaskets, and mounting hardware.
