Well i had an hmf slip on, on my stock 300 header, bumped to a 125 main jet. i liked it but it was way to loud for where i rode. so i sold it.
my friend put a 350x motor in his 250x and couldnt use his fmf header. i bought it and made it fit my stock silencer. long story short, it needed jetted to a 128 because it was making more power. so i got more gains with just a header and its quiet.
:macho
