Exhaust on 40i

I picked up mine on Saturday and noticed that only the driver side exhaust pipe is letting out smoke while the passenger side doesn't have anything coming out. I'm wondering if this is how it's designed or is something wrong. I also have a 540 and it has both pipes working all the time.
