Can you wrap a performance pipe and then put on an oversized silencer and make any headway on decibels? Plus figure out an air intake that has highflow but silence ? Isn't going backwards to a stock exhaust give up all the resonance ie hitting the pipe? Yea I know that what ever Vespa creature is hitting 50 with basically no suspension is kinda punitive , I would think a master at your level would simply want a quiet 38-42 mph wonder. Show us how that happens.
