Grimspeed Stage 2 Power Package (08-14 Subaru STI)

GrimmSpeed Stage 2 Power Package

The GrimmSpeed Stage 2 Power Package is a well-rounded kit, offering increased power and torque output thanks to reduced restriction before and after the turbo, as well as a more aggressive street presence thanks to the intake and exhaust tones. The upgraded GrimmSpeed 3-Port Boost Control Solenoid offers more accurate and more responsive boost control and is a must when having your vehicle professionally tuned. The GrimmSpeed Intake adds an additional performance increase by reducing pre-turbo restriction, which allows your turbo to build boost more quickly and more efficiently. The GrimmSpeed Downpipe replaces the extremely restrictive factory downpipe and catalytic converter with high quality 3” diameter stainless tubing and a high-flow catalytic converter

The divorced wastegate design of the Downpipe offers superior boost control and is the perfect complement to the Electronic Boost Control Solenoid. Over stock, the Downpipe replaces two restrictive catalytic converters as well as increases the tubing diameter. The result is a decrease in restriction after the turbo, an increase in turbine efficiency, and will further decrease time to spool as well as increase boost pressure.
