How audible should VTEC be on a bog stock VTI-R(no exhaust, no pod filter mods), I haven't owned a DOHC VTEC before, only a VTi, so I'm a bit of a noob to the VTI-R Teg and don't know if I should be able to easily hear when VTEC comes on....or is it only really noticeable with breathing mods to exhaust and filter? I'd like to be able to it bark when I'm up it!
