Stock puch powerband with stock pipe goes to 6,500 +rpm, With aftermarket pipe could go way higher like 9-10,000 rpm

Unported cylinder with stock exhaust with one extra hole in it . Oh yeah junk airbox and snorkel thrown away as usual and mesh filter used, that’s what stops a puch from reving,

Sounds like a lot more then 4,000 rpm to me:
