XPT Stage 1 - 2008 WRX MT
[XPT1401A]

Makes the car faster, easier to drive and significantly more fun. With the boost reserved for 60% or more throttle, you can drive like a civilized person when you need to, but peddle it for fun. Well worth the money for drivability reason alone. It took a twitchy quick car and turned it into a smooth fast car. Thank!
