Tomei EXPREME Exhaust Manifold Unequal-Length - Subaru WRX / STI / Forester (GC8/GDB/GRB/GVB) - EJ20 / EJ25 Single Scroll

The Tomei EXPREME Unequal-Length Exhaust Manifold replaces the factory 4-2-1 layout with a high-efficiency 4-1 design, improving turbo response and spool.

The unequal-length runners use exhaust pulse scavenging to draw gases from adjacent cylinders, giving strong mid-range torque and the classic boxer rumble. Built from SUS304 stainless steel, it weighs 7.3 kg against 10.5 kg for the factory manifold.

Note: For single scroll turbo applications only. For twin scroll EJ20 STIs see the Tomei EXPREME Twin Scroll manifold.
