2018-2020 WRX STi Stage 2 Hard Parts Package By MAPerformance

We are excited to offer our Subaru STI Stage 2 Performance Package! Throughout the R&D, testing 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, 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 is required from the turbo and less stress on the engine to achieve the higher power levels. 

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

Great product

This has made the car feel like it should from the factory. With stock exhaust it’s perfect. Also customer support has been more than amazing.

So far so good.

Solid workmanship no issues thus far. Not a huge fan of all the popping it does now though! Worth the money for a few extra horse.

Absolutely Wonderful

I received my Stage 2 package five days after ordering it. I was so excited to get it in the car, but I had to wait until I had a chance to do the work. By god, I'm glad I went for this. Not only does the car sound amazing now, but it also drives like a dream. The amount of power increase is undeniable. Before, I could go WOT and have a little lag on the turbo and then start to get up to speed, now if I go WOT in any gear, I'm thrown back against the seat. Made my car so much more fun to drive, and the OTS map has held up very well. Truly a well-put-together package, and I cannot stress to you the absolute pristine quality of the parts and the amazing customer service I received from MAP.

Awesome stuff

Everything fit perfectly and has been great so far. Interested to see if a front mount intercooler will work with this intake.
