GRIMMSPEED POWER PACKAGE - STAGE 3 - 15-21 WRX
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 they're design theories are compatible, consider starting with one of our excellent Staged Power Packages based on your goals!
The GrimmSpeed Stage 3 Power Package represents the pinnacle of bolt-on performance for your 2005-2009 Subaru Legacy GT. This package includes everything from the Stage 2 package with the addition of the famous GrimmSpeed Top Mount Intercooler. Along with the additional power and torque that your car will be producing thanks to the upgraded intake and exhaust components comes heat in the form of warmer charge air temperatures. It’s important to reduce these temperatures and increase the oxygen density of the pressurized air entering your engine. This additional oxygen will help protect your LGT from knock and allow your tuner to take full advantage of your Stage 3 setup.
On the intake side, 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.
Finally, on the exhaust side, the included GrimmSpeed Downpipe replaces the extremely restrictive factory downpipe and catalytic convertor with high quality 3” diameter stainless tubing and a high-flow catalytic converter.

The GrimmSpeed Stage 3 Power Package features the same components of the Stage 1 Package, but further increases the performance of the Turbocharger with the inclusion of the J-Pipe. The free-flowing design of the J-Pipe offers superior boost control, and is the perfect complement to the Electronic Boost Control Solenoid. Over stock, the J-Pipe replaces a restrictive catalytic converter with a high flow unit 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.
- NOT COMPATIBLE with CVT Automatic Transmission
- It's important to note that all GrimmSpeed Staged Power Packages require a proper tune.
- Careful attention to installation of the intake tube, air filter, clamps and MAF sensor/o-ring otherwise leaks may occur.
