Get a cnc head. I sawed off stock muffler. Removed baffle. Expansion muffler wouldn't fit. No difference except loudness. Have you ported the head? 33tooth rear sprockets add a bit... Also I have high performance CDI with a 4 prong high performance spark plug.. It'll do 60mph easy but cops look at u more when passing vehicles. Also might wanna invest in Kevlar tube liner inserts and 12 guage spoked rims add more durability. This is my 4th bike build. It's a 80cc ported and a CNC polished head with reed valves.
