don't matter...and yes they will ticket the Harley's too...
the story goes...
we are all at Malibu Kitchen, big pack of Ducs. Two moto cops pull up and give us fair warning, explaining that the noise tix are coming down from the top and they are to tix all aftermarket pipes. Motocop then sites every aftermarket name you can think of...(obvious street rider? ;D) and then we asked about Harley's...they, yes, are just as likely to get cited.
Recently, Ryan and I were flying down Mullholland, cop passes us, turns around, passes me (

) and pulls Ryan over...radar NOT on...but he gets Ryan for pipes...I had not changed mine out, rolling stock=no fix it tix...
Ryan later told me he makes NO change to the pipes, rolls out to Malibu and gets the fix-it tix signed off on the Termis... [laugh]
