It's a half hour job to swap the Y-pipe back to the stock one. Yes, there can be a fuel smell that invades all your clothing. The bike will also be louder.
On a positive note, loud exhausts are known to add to your level of coolness and the fuel smell adds to your masculinity, unless you're a lady in which case it makes you an even hotter biker chick.
Biggest positive of all is you will stop cooking your leg when slow riding on a hot day.
