2018-2021 WRX STi Stage 2 Hard Parts & Tune Package By MAPerformance
We are excited about the official release of our Subaru STI Stage 2 Performance Package which, when combined with the included Stage 2 optimized Accessport Tune (currently 2018 models only), is a very potent performance upgrade! Throughout the R&D, testing and calibration phases of the EJ powered 2015+ STI platform, we have been thoroughly impressed with the performance gains from each hardware modification. Better yet, our MAPerformance STI downpipe and air intake systems were designed to support considerably higher power levels allowing for future growth; the included USA Made performance parts support power levels any bolt-on turbo upgrade can throw at them!
When comparing our MAPerformance Stage 2 power package to a stock STI running our Stage 1 Tune, there are many advantages far beyond the improved sound and raw power. Not only are the power and torque gains inherently impressive, but it’s also important to note how much less work required from the turbo and less stress on the engine to achieve the higher power levels.
Disclaimer: This product is intended for off-road use only. As sound level and emissions laws vary based on location please consult your local authorities for additional information.
