hey guys i have an rb20, standard bov, but with a k&n pod filter. i swear to god the pod lets out a sound as loud and nice as most bovs i have heard. a mate of mine with an sr20 bought the same pod for his car and it started makin a similar noise. i really think it depends on the type of pod you have!
dont bother with the atmo, it aint worth the defect....my 2c
