Intro Hey, I just got my first Subaru about a week ago and it's got some issues. It's a 2011 WRX, I bought it from a ford dealership, and it's not stock. Whoever had it last had subs (they left the wiring in the car), gave it an aftermarket exhaust, an aftermarket BOV, and left me with the COBB...

My 2011 wrx hatch has started to make a sound when on throttle around 3,500-4,000 rpm. it sounds like a blow off valve but only happens when I'm on throttle and actually driving, not stationary. It lasts for longer than a typical blow off valve though. My car is stock besides a cat back exhaust...
