I hadn't noticed this before the other morning. I backed "The Beast" out of the garage to let it idle/warm up a bit before changing the oil. The air temp was around 40 degrees so in the rearview mirror I could see some exhaust 'smoke' coming out of the pipes. I got out and walked around to the back of the car to look at it. I was surprised to see only two of the four openings were 'puffing'. I expected to see 'smoke' wafting from all four of the tips.

Is that correct for a bone stock exhaust system?

If so, would it be harmful to somehow open up the other two? Seems silly to have four openings and only two functional.
