Description

Tomei has long been recognized for their precision Japanese engineering and dedication to performance. The new Tomei V2 Full Cast Turbo Outlet Pipe for RB25DET and RB20DET engines continues this legacy with a complete redesign focused on strength, flow efficiency, and reliability.

The updated V2 model offers 1.7 times larger internal volume compared to the factory outlet, increasing from 750cc to a massive 1284cc. This substantial increase in flow capacity greatly improves turbo efficiency by reducing backpressure and optimizing exhaust gas velocity. The result is sharper throttle response, faster turbo spool, and improved power delivery across the rev range.

Built using high-strength stainless steel and a one-piece full-cast construction, the new outlet eliminates all welded joints found in previous versions. This casting process not only enhances durability but also ensures a smoother internal surface for unrestricted gas flow.

Designed for seamless integration, the Wide Mouth 3-inch (φ76.3mm) outlet provides a step-less transition to your front pipe, allowing exhaust gases from the turbo to exit smoothly without turbulence or loss of speed. Whether used on a tuned street car or a high-powered track build, this upgrade offers a perfect balance of strength, precision, and performance.
