Tomei EXPREME Equal-Length Exhaust Manifold for EJ25 single scroll turbo Subaru models. 4-2-1 isometric design with optimised pipe diameters eliminates exhaust interference for peak power gains and high-RPM performance. Lost-wax cast SUS304 stainless steel collector ensures crack-free durability and smooth gas flow. Produces a higher-pitched racing exhaust note distinct from the traditional boxer rumble. Over 5kg lighter than factory at 8.85kg. Includes exhaust bandage, gaskets and bolt kit.
