TOMEI EXHAUST MANIFOLD EXPREME 86/FR-S/BRZ FA20 UNEQUAL LENGTH

TOMEI EXHAUST MANIFOLD EXPREME 86/FR-S/BRZ FA20 UNEQUAL LENGTH

This TOMEI EXPREME manifold is a functional upgrade, not an engine-bay decoration. It replaces the factory manifold with a smoother runner and collector layout designed to move exhaust energy more efficiently and give the engine a more responsive, purposeful character.

TOMEI’s exhaust hardware is developed around real Japanese performance applications rather than a one-size-fits-all header. The flange placement, runner layout, and routing are built for the exact engine and chassis configuration named in this listing.

Why Choose It?

• Smoother runner transitions and collector routing help exhaust energy leave the cylinder head more efficiently
• Vehicle-specific flange placement avoids the compromises of a universal manifold
• Stainless-steel construction handles repeated heat cycles and gives the engine bay a proper finished appearance
• Improved runner and collector design supports better scavenging and a more responsive naturally aspirated setup

Sound

The unequal-length runner layout is what preserves the familiar uneven Subaru pulse and traditional boxer rumble. The manifold can make the car sound sharper and more defined, especially when paired with a freer-flowing exhaust.

Construction

• Stainless-steel construction
• Vehicle-specific pipe routing and flange placement
• Precision-welded joints designed for repeated heat cycles
• Application-specific runner and collector layout
• Built for the engine and turbo arrangement stated in the title

Configuration Details

• Equal length: balances runner length and exhaust pulse timing for a smoother, more even tone and consistent cylinder-to-cylinder flow.
• Unequal length: retains uneven pulse timing and the traditional Subaru exhaust character while replacing the restrictive factory manifold.

Fitment

• Application: 86/FR-S/BRZ FA20 UNEQUAL LENGTH
• Product type: Exhaust Manifold
• TOMEI part number: TB6010-SB03B

Please note: Confirm the exact chassis, engine, market, body style, turbo layout, and Type designation before ordering. Performance exhaust components may change vehicle noise and emissions compliance, and supporting modifications or calibration may be required depending on the application.
