Tomei EXPREME Exhaust Manifold Twin Scroll - Subaru WRX STI (GDB/GRB/GVB/VAB) - EJ20

The Tomei EXPREME Twin Scroll Exhaust Manifold uses a 4-2-2 layout with Φ42.7–45.0 mm SUS304 stainless steel runners, designed to feed a twin scroll turbocharger for improved power, torque and throttle response across the rev range.

At 9.7 kg it is lighter than the 13.1 kg factory manifold, while using thicker 2.0 mm pipe walls for durability.
