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

STG2 FOR THE WIN

Great quality in product and easy install at least for me . Shipping carrier was careless with my parts but customer service at MAPreformance took care of me promptly and got me what was missing. Requesting OTS tune was simple and didn’t take long to receive. ( 24hr turnaround ) My STi runs super great btw and no abnormal feedback knock and DAM reading . Get you one. JUST DO IT !

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.

2017’ STI with the Stage 2 power package is amazing!!

Huge props to MAPerformance, with the Stage 2 power package!! The car is night and day. The biggest improvement is daily driving. I find myself needing less throttle input to keep up with traffic. It even seems like the car leaves the light with less effort. MPG’s have slowly been climbing and you can feel the added power.

Straight forward install. Added intake noise is nice. Catted down pipe sounds amazing!! Currently running a Tomei UEL, Hooker Blackheart axle back, and down pipe. Stock mid-pipe.
