I own a loud a$$ Harley,the reason is b/c people everywhere change lanes and NEVER turn there heads to see if there is no one there.
I too sometimes leave for work @ 5:30am,I'm sure my neighbor's don't appreciate it but I try to short shift it to keep the RPM's down that's the best I can do.
But do I feel bad having loud exhaust "HELL NO" it has saved me from serious injury,for those that don't like it I say to each there own,everywhere I've lived cops will bust the crotch rockets balls but never once have I been harassed or pulled over for loud exhaust.
