In ten years the twin underseat exhausts will look just as dated (styling is already changing to under bike mufflers) and then you'll want to change the bike back to stock so it doesn't look like some wannabe '90s bike...
Kind of like all the guys that "updated" their bevel drive Ducatis back in the day and are now searching out parts to make them look correct again!
It's your bike, do what you want, but trying to make a Paso look like something it wasn't intended to be very rarely works in my eyes. IMHO the bike in the link posted above looks hideous...
