After 1month of having all parts installed: ets catback exhaust, ets cold air intake and Cobb stage 2 running. I absolutely love driving my wrx everyday. So Much more power added, the sound is amazing. A quiet idle but roars louder and louder as throttle increases. Everyday I turn heads when driving by and have been complemented " awesome car man" at least 100 times. 4real thank you ETS for your part in making my car what I wanted it to be, A joy to drive.
