Ok, so this morning I've been a busy little bunny, I removed the airbox resonator and fitted my pipercross panel filter, easy enough if a little time consuming due to things being held in place, even with bolts removed, but meh.
Anyway, it's maiden voyage was taken, the acceleration is improved now and vtec sounds awesome (for the 1.8 anyway). My question is:
Under acceleration there is a loud whistling noise, kind of like someone blowing over an open bottle sound, that gets very loud once vtec kicks in. Is this normal after the above mentioned mods?
Many thanks
