Hey all,
Me and my mate were having a discussion today about why my stock r33, doesnt make any BOV sounds and why my spooling is very quiet, i was to think mabye it was because i am running stock boost, therefore not much pressure to make much noise, however my mate thinks it could have to do with my stock airbox, i was just wondering how would i make my BOV louder? i put my mates blitz BOV too see how it sounded and still couldnt hear anything at all.
