2015-2021 Subaru WRX STI Stage 2 Power Package – Red by GrimmSpeed
The beauty of the GrimmSpeed Staged Power Packages is that all of the included components were designed and tested to work well together as a complete system. Instead of piecing together parts from many different manufacturers and hoping that their design theories are compatible, consider starting with one of our excellent Staged Power Packages based on your goals!
The GrimmSpeed Stage 2 Power Package is an excellent place to start when modifying your 2015-21 Subaru STI. 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 performance increase by reducing pre-turbo restriction, allowing your turbo to build boost faster and more efficiently.
The GrimmSpeed Stage 2 Power Package features the same components of the Stage 1 Package, but further increases the Turbocharger’s performance by including the Downpipe. The divorced wastegate design of the Downpipe offers superior boost control and is the perfect complement to the Electronic Boost Control Solenoid. Overstock, 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 in time to the spool as well as an increase in boost pressure.
