Awesome product!
Fitment was perfect! Not overly happy with the Gaskets that they come with...Blew out within 5000 miles...But header/uppipe combo is awesome!! Very happy!
AWESOME
2011 WRX fitment perfect ! quality workmanship! thanks IIR and friends in Indiana who know Subaru's
Awesome Header
Overall this is a great header and up pipe combo. I can't really say for sure what kind of extra power I made with it because It was installed with many other parts. But I did make 370WHP on 93 octane with and AMR CXR500 turbo and other supporting mods. Only downside to the combo is the Gasket it comes with, Buy an OEM style gasket with your purchase of this header for safety. The one it came with blew out on the first pull I did. Great header and UP pipe though!
awesome

The all new Agency Power stainless steel unequal length header kit is now available for your Subaru. A special designed collector enables perfect flow into the uppipe providing faster turbo spool and increased horsepower. The AP header features polished 304 stainless steel for a show quality finish. The header has CNC machined ½ inch thick flanges and includes everything you need to bolt directly on to your turbo Subaru. Installing the header will not only gain you about 15 wheel horsepower, it will also change the tone of your Boxer engine to a deeper and more aggressive sound.
Agency Power offers their unequal length header with or without their uppipe. Maximum gains can be found with their performance uppipe.
- Note:
- Head to uppipe gasket supplied
Fitment: 02-12 WRX/ 04-12 STi
Part #: AP-GDA-175

Header was great build / performance quality ... no fitment issues .. even packaged well to avoid damage during transit. Very nice piece without killing your wallet. Best part is 2 bolt flange will allow you to mate up to a rotated kit.
