Tomei Expreme UEL Exhaust Manifold Ver.2

Tomei Expreme UEL Exhaust Manifold Ver.2 - GR86 / BRZ / FR-S

The Signature Boxer Rumble & High-Efficiency Flow

Transform the character of your car with the Tomei Expreme UEL Manifold. This Version 2 update is the result of extensive dyno testing and real-world track development in Japan’s Z-Masters race series. By utilizing an unequal length (UEL) 4-2 collector design, Tomei has optimized the exhaust pulses to produce the deep, iconic boxer sound that the platform is known for. Constructed from high-grade SUS304 stainless steel with a larger 45mm pipe diameter, this manifold reduces backpressure and sheds over 5 lbs of weight from the front of the vehicle, resulting in sharper throttle response and improved front-end agility.

What’s Included in the Box:

- UEL Exhaust Manifold: (1) SUS304 Stainless Steel assembly.

- Exhaust Flange Gaskets: High-quality multi-layer gaskets for a leak-free seal.

- Mounting Hardware: Full set of studs, bolts, and nuts for installation.

- Titan Exhaust Bandage: Premium basalt-fiber heat wrap to control engine bay temps.

- Exhaust Bandage Bands: Stainless steel zip ties for the heat wrap.

- Bolt Smooth Paste: Specialized anti-seize for high-heat exhaust hardware.

The Tomei Advantage

- Iconic Boxer Sound: The unequal length design specifically targets the exhaust timing to create the aggressive, low-frequency rumble that equal-length headers eliminate.

- Optimized 45mm Diameter: Increased from the Version 1 design, the 45mm primary pipes provide a greater volume of airflow, supporting higher power levels on both stock and modified engines.

- Precision Lost-Wax Flanges: The manifold features custom-designed, lightweight flanges produced through a lost-wax casting process, ensuring maximum rigidity and a perfect warp-free fitment.

- Comprehensive Heat Management: Includes Tomei's signature Titan Heat Wrap to keep heat inside the manifold and out of the engine bay, protecting sensitive components like the alternator and plastic sensors.

- No-Crush Collector: The 4-to-2 merge section is designed with smooth transitions and zero restrictive crush points to maintain maximum exhaust velocity.

- FA24 Optimized Clearance: The Ver.2 layout was specifically tweaked to ensure perfect clearance around the 2022+ FA24 oil pan, making it a true cross-generation performance part.

Precision Tip: If you are installing this on a 2013-2021 (FA20) model, Tomei recommends pairing this with the Expreme Joint Pipe V2 for a perfect, tension-free fit. Because this header deletes the primary catalytic converter, an ECU reflash or tune (such as EcuTek) is highly recommended to maximize power gains and prevent a Check Engine Light (CEL).
