TOMEI EXHAUST MANIFOLD EXPREME WRX/STI EJ TWIN SCROLL EQUAL LENGTH

TOMEI EXHAUST MANIFOLD EXPREME WRX/STI EJ TWIN SCROLL EQUAL 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 exhaust routing can help the turbo respond more cleanly when paired with the appropriate supporting parts and calibration

Sound

The equal-length layout smooths out the exhaust pulses, giving the engine a cleaner and more even tone than an unequal-length manifold. It trades some of the traditional Subaru rumble for a more purposeful, higher-frequency sound.

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.
• Twin-scroll: keeps the divided exhaust pulse path required by the named twin-scroll turbo setup.

Fitment

• Application: WRX/STI EJ TWIN SCROLL EQUAL LENGTH
• Product type: Exhaust Manifold
• TOMEI part number: TB6010-SB01A

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.
