I'm probably imagining things but after hearing it in every possible intake configuration I have, the questions start rolling. Any time I'm flat on the accelerator and cross the 4500/4600 rpm threshold, the sound very clearly changes tone, not in any way same as a real VTEC, but still in the same kind of sound. It also sounds funny and conspiracy-y because 4600rpm is where peak torque is produced on the D14a8 haha. Still, this is no way a serious post, more like a gimmick for fellow D14 owners to try and find it in their cars and confirm it, have fun lol
