Moped Army

i just bought a new tomos streetmate a couple of months ago, i only have 130 miles on it because i didnt get my license yet. I was wondering how much i could do in nj on my moped to get it to go faster. i was told that the streetmate can easily go about 32-35 mph and a turbo pipe adds about 5-7mph. so thats about 40mph and i was wondering if theres anything else legal i can do to add about 5 more mph because anymore and i wouldnt have enough braking power. thanks for the help.
