Tomei Full Cast Turbo Outlet Pipes 421001

Tomei Full Cast Turbo Outlet Pipe for Skyline GT-R RB26

The Tomei full cast turbo outlet pipe is engineered to reduce secondary back pressure and improve exhaust flow for the Skyline GT-R RB26. The factory outlet is restrictive and can create excessive back pressure, limiting performance at higher boost levels. The Tomei design supports significantly greater flow and helps relieve load on the compressor housing.

The updated model clears surrounding intake piping and the turbo compressor housing without the indentations seen on the previous version. The use of high grade SUS316 material increases strength and thermal resistance compared to the earlier SUS304  design, ensuring reliable operation in demanding conditions.

Improved Installation Access

For easier installation, the outlet pipe includes a formed clearance section near the flange bolts. This makes it simpler to reach both bolts and nuts during fitting, offering a quicker and more convenient installation experience.

Wide Mouth Step Free Design

The outlet features a wide mouth opening with a smooth connection to a seventy mm front pipe. Exhaust gas is directed straight toward the front pipe without reducing flow speed, improving response and consistency under load.

The latest release also features a finish that matches the Tomei full cast exhaust manifold, providing a clean and unified appearance in the engine bay.
