4-2-1 Exhaust Manifold

The Tomei Expreme Equal Length Exhaust Header is engineered for a 4-2-1 layout with a SUS304 stainless steel construction and a lost-wax collector design for smooth exhaust flow. This header is significantly lighter than the factory manifold, weighing 8.85 Kg versus the OEM's 13.9 Kg. It is specifically designed for vehicles equipped with single-scroll turbo systems and is compatible with EJ205, EJ207, EJ255, and EJ257 engines. Installation requires replacing the oil pan or oil strainer on GC8, GDA, and GDB models. The package includes the exhaust manifold, a turbine support pipe, titanium exhaust bandage (50mm x 15M), secure bands, gaskets, blind bolts, installation manual, and two TOMEI stickers. To maximize performance gains from this equal-length header, ECU tuning is recommended. Professional installation is also advised for optimal results. Compatibility is primarily for JDM vehicles, and fitment is not guaranteed; buyers should conduct their own research before purchasing. After-sale support does not extend to installation assistance.
