2015-2017 WRX STi Stage 2 Hard Parts Package By MAPerformance

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

Map tune

I honestly love the parts! Super easy to install. Everything fit perfectly. The only down side was I found out after i installed the part the map tune was no longer available. So now I gotta find a local shop to tune it for me. But I guess I should’ve inquired about before buying anything.

GREAT PRODUCTS

The stage 2 package is a must for the STI. The car has come alive and is a blast to drive and a real head turner now. The products are extremely good quality and well made. I couldn't be more happy with the purchase. My STI now has turbo whistle from the exhaust, and very audible whoosh from the engine. No more rev hang, gets into boost much faster and holds boost much better now. Absolute joy. And I ordered on a Wednesday and products arrive Friday afternoon. Extremley fast shipping and great customer service.

This Is How It Should Be

Had enough time to install the Stage 2 and it’s a night and day difference. The response in S# makes the little kid in me grin from ear to ear. Great product quality, best salesman (Tony), and overall a great buying experience. Will definitely buy from you guys again. Hurry up with a Stage 3 package, pretty please lol
