When my decat went on my old Mk1 180, it sounded better and felt stronger lower down the rev range - just breathed better - (but was fitted after a pipercross induction kit which in itself gave 6bhp improvement - dyno'd).
Standard induction on the 180 simply does not appear to be good enough and should be one of the first things to improve IMHO if you're looking for more power.
