Well at almost 60 degrees here in NY . so for the first time i get to ride with all new mods i did and i gotta tell ya these HMF are pretty darn Loud a little louder that i thought (i had a full muzzy on my ZX11 and these are much louder , and i also added raising link of 1" and i'm wondering if it's me or do i feel the riding position is a little different in city stop and go ,,seems like my head has to lean back a little more than before ..Then again have notbeen on the bike for 3 months .. i do love the feel of acceleration difference that the pcIIIusb and pipe combo ...lets see if the wife can deal with the extra noise..
