Efficient High Flow Design For Both RB20 & RB25 Engines
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.

■ WIDE MOUTH, STEPLESS SMOOTH PORTING
The stock outlet pipes 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 INCH (φ76.3mm) 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.
