Hi all...I have a 2011 WRX just purchased a month ago...22K miles. Only aftermarket mod is COBB intake (it has been tuned). Only thing I have "done" to the car is put a factory heat shield on the car that was missing.
Just started hearing clicking type noise...almost straining type of sound (not a grind or clank) upon acceleration. Also, only when depressing pedal when launching after shifting into a new gear. Almost sounds like coming from backseat under car. Sound is faint.
Any ideas? Sorry for vague description, but thought I would try. Car runs great otherwise.
