2015-2017 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, 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. 

2015-2017 Subaru STI Stage 2 Kit Features

  • Capable of 331whp/347wtq (+59whp/+58wtq over STOCK!)
  • 304 Stainless Steel Components
  • 100% Mandrel Bent Piping
  • 3" Piping For Improved flow
  • Fully Tig Welded and Back-purged
  • USA MADE

Top Notch

I bought this kit and run the MAP 93 Octane OTS Map. I am exceedingly pleased with everything. The fit is impeccable and the install was straight forward. I have been modifying cars for about a decade and it was one of the better installs I've done in terms of fitment. The power increase is substantial and the tune is VERY good. Very little knock driving around and virtually zero knock events under heavy load and boost. I really do not think I could be more pleased with the stage 2 kit from MAP, honestly. The MAP customer service is some of the best I've ever experienced too. Extremely satisfied with my purchase. I'll be an MAP customer for life.

The Best Thing You Can Do For Your Car

This is probably the best thing you can do for your car in terms of performance and economy(insert *this is how it should have come from the factory statement here*"). I was running the Cobb Stage 1 tune and a catback for the past 4 years of ownership and decided to pull the trigger on the MAP stage 1 91 OCT. tune and I was a believer. I was having some issues with my catback due to an improper install(I was missing the adapter and inexperience) and went with an upgrade/fix in the form of the MAP Stage 2 package. At the time, this power package wasnt in stock but Tony from Sales really pulled through and gave me a fantastic deal on the package. He got it built and shipped to me lightning fast(I'm in Canada). The car feels like a completely different car and goes like a bat out of hell. The turbo BPV sounds add to the experience and tunnel blasts have never been the same since. The car is not only faster, more responsive and more competitive with everything else on the street but also runs a lot smoother than it did from the factory. I highly recommend anyone getting this upgrade for their car as one of their first upgrades.

Cost effective and you can keep stock exhaust

Overall a good product and worth the money. Not a perfect fit out of the box, no aftermarket kit has been in my experience. I took my previous 2006 STI to Cobb OTS stage 2 with catless dp & exhaust. It was painfully loud on long trips. This setup gives you great torque and hp gains without requiring aftermarket exhaust. My 2017 STI is now louder than stock and definitely a loud car with this set up, but much quieter compared to an aftermarket exhaust. Watch the MAP youtube video on the stage 2 tune for this car. MAP rep immediately addresses how loud the car is with aftermarket pipes. Unless you want a headache-inducing cop magnet, go for this cheaper alternative that allows stock exhaust. I’ve been on both sides, you get all the power and still get plenty of boxer rumble from this with stock pipes. My $.02.

A superior complement to an already legendary platform!

The title says it all. This shop has done their homework and it shows not only in just their craftsmanship, but also in the effort that went into creating an OTS tune that maximizes your stage 2 setup without sacrificing reliability. Throttle response is improved greatly, boost sets in with a healthy curve to redline in both sports & sports #. I mode is also still active if you want to cut some of the added boost to save gas! Best purchase I’ve made for the car!

How a modern STi should come from the factory

Over the years Subaru hasn't done much to increase the power of the STi to keep up with the rest of the market. I purchased this package along with an exhaust and AOS for my daily driver. It has been the perfect setup for a fun, reliable daily, with a relatively small amount of money invested. I would recommend this to anyone picking up a new STi looking for an easy an convenient bump in power.
