Grimmspeed Stage 2 Power Package - 2008-2014 Subaru STI
If you’re ready to start making some serious horsepower, then you will be pleased with the Grimmspeed Stage 2 Power Package! All of the included components have been designed to work together seamlessly to provide you with increased horsepower, torque, as well as improved throttle response.
Starting with the Grimmspeed Cold Air Intake System. This intake system replaces the factory restrictive airbox that came from the factory in your car. Although it does its job, it is considered to be a highly restrictive unit. Grimmspeed relieves this issue with their Cold Air Intake System that allows the turbocharger to breathe in copious amounts of air which will add more horsepower, torque, and will provide an aggressive tone under acceleration.
To complement the intake system, Grimmspeed provides their Catted Downpipe. This downpipe has been designed with minimum bends which reduce turbulence under acceleration. This is a divorced wastegate style downpipe that has 3” piping that is fabricated from 304 stainless steel. The designed will free up a substantial amount of horsepower and torque, and will come with an implemented 300 cell catalytic converter. Once installed, not only will you appreciate the power gains, but you will also enjoy the more aggressive sound coming from the exhaust system.
To help improve boost control and boost response, Grimmspeed will include their 3-Port Electronic Boost Control Solenoid. This is a direct plug and play unit that installs into your factory harness to improve boost response and to reduce turbo lag. This solenoid works safely with your ECU, and takes about 15 minutes to install.
To top off the Stage 2 Kit, a Turbo Heatshield is provided to add extra protection to surrounding vulnerable components in the engine bay, and to shield them from excessive heat. This heat shield will come in a nice bare metal finish, and will come with Grimmspeed’s logo on the side.
Finally, a Grimmspeed License Plate Frame will be included to to show others what kind of quality parts you are running in your vehicle.
