Performance Mods:
-Borla Hush 3" Catback
This thing was a beast to install. Glad Borla sent new hardware, I twisted both flange bolts in half. It was totally worth it though, I couldn't be happier with how it looks and sounds. Like it's the way the car should have sounded in the first place. Even from cold start it sounds perfect, like a recording.


-Front and Rear Strut Bars
These are STi replica strut bars. They fit nice and solid. I did have to go get some ammonia hose for bushings between the front bar and the bolt though. All in all I'd say they ride pretty well.
Front (this picture also shows my BOV, grounding kit, and dirty, dirty engine bay):

Rear:

-Hotchkis Tubular Swaybars and Perrin Pillowball Endlinks
Definitely the most worthwhile suspension mod for a WRX. These sways are 1" tubular, and the rear has 3 stiffness settings. They also come with upgraded mounts. The endlinks are solid aluminum, with spherical bearing mounting. I have yet to try the stiffest setting, I was starting to get snap oversteer on medium.

This pic shows the diameter difference from stock.

-Cobb AccessPort ECU Tuner
Not really much to show here, but I'll put up a picture of the unit itself once I get a chance.
-Ver. 7 STi catless uppipe
Again, not much to look at, but I'll post a pic soon.
