you should be getting at least the same as mine. i havent pushed mine for outright power my exhaust is still quite quiet with a silenced de cat at around 96db. so its got enough power but is very nice and relaxing on a run :Thumbs-up

mine was 300 atw with stock ports and twins @ 0.9 bar so could be true
