Tomei Expreme Turbine Outlet Dump Pipe

Efficient High Flow Design For Both RB20 & RB25 Engines

The Tomei Expreme turbo dump pipe features smooth inner walls, a high flow capacity, and an easy to install flange design for an easy direct bolt on application. Compatible with the stock turbo and the Tomei ARMS Turbo, this turbine outlet will contribute to improving the power output. Designed to suit a Φ76.3mm front pipe.

Wide Mouth Stepless Smooth Porting

The stock outlet pipe's mouth is partially blocked at the port bypass side. This design is for low engine speed response. We’ve enlarged this section to improve power gains. By optimizing the shape of the enlarged area, we were able to prevent the loss of both torque and power in the low engine speed range. 

3" Pipe Compatible

The internal diameter has been enlarged by 120%. This will significantly drop exhaust back pressure.

140% Larger High Strength Flange

Ease of Installation

Designed to be a hassle free installation. We have incorporated a dimple in the pipe where the bolt for the flange is located. To allow ease of access to both bolts and nuts to allow a quick, trouble free bolt on application.
