Hey guys, i dunno why but i realised my BOV "WOOSH" sound has decreased at the end when i take the foot off the throttle. I think it has decreased after installing a K&N Air Filter, but inside the car it sounds so loud but when i put the windows down it sounds so weak!!!!! AND because im a BIG FAN OF Dump Valves making those "WOOSH" sounds, is there other alternatives of making it louder???? Should i change the BOV for dat? or get a bigger trumpet for BOV?
