Subaru WRX Stage 2 Upgrade Kit | 2015-2020 FA20 WRX MT Performance Package

Great products. Well manufactured, definitely noticeable power increase. And it sounds amazing!

The install was not bad at all, and the power increase is very noticeable. I've had this installed for about 9 months now, and it is running smooth and strong. The tune seems to make it come alive, the sound is fantastic, and I just love driving my car every day that much more now. Great product!

Background: 2020 WRX Premium 6MT 41K miles. Completely stock to stage 2. Installed at home with hand tools and on jack-stands.
Product: Everything came well-packaged and shipped quickly. Everything was in perfect condition upon arrival. The Fit and finish were perfect.
Install: The installation is straightforward with 1 massive exception. The top two nuts/studs that hold the factory catalytic converter to the turbo are an absolute nightmare. WD-40, a torch, 6-sided swivel socket, extensions, a pipe, and about 4 hours were required to break them free. If your car has many more miles than mine, good luck.
Tuning: This was my first time using COBB. I have used HPTuners and EFI-Live in the past. COBB's GUI is lacking but it gets the job done. The process was easy. Download their software to your computer. Download firmware updates. Download the tune from MAPerformance to your computer. Upload the tune to the Accessport. Follow COBB and Accessport instructions to upload the tune to your car.
Test drive: :) The money, time, blood, and sweat were worth it. (Now I wait to see how many tickets my wife gets) The new and improved turbski noises gave me a semi. My kids complained about the exhaust so that too was perfect. (It drowns out their whining.) The car's boost gauge was reading a new peak boost of 23.4 psi. There was a great improvement in HP, TQ, and overall drivability over stock. It pulls solid all the way to redline. That weird dead spot around 4500rpm is gone. The car no longer falls flat after 5252rpm. This really is how the car should have come from the factory.
Recommendations to MAPerformance: Provide replacement nuts for the J-pipe install. Maybe even offer replacement studs/bolts to replace any that break as a dropdown option when ordering the kit. I was patient and methodical when removing those Cat bolts. However I can imagine many people will either round off the nuts or shear the stud off. Giving the option for replacement hardware at the time of purchase is going the extra mile.

Amazing product. Everything was great quality. The sound is absolutely prefect. Great sound at idle and very little drone while cruising. But when you lay it to it you can really hear it. Also its no so loud that you have to worry about the neighbors. Would highly recommend for anyone that wants great sound with amazing performance. The only down side is that didn’t send me a sticker (hint hint) :) would definitely recommend this to anyone!

Product quality is awesome. Fit and finish was perfect. If you order this kit, be sure to request the stage 2 tune. It is included, but you still have to request it with the tune form on the site for it to be emailed to you. I didn't know that, but customer service saved me. Overall it was worth it. Thanks MAPerformance!
