Default Magnaflow configuration??

What is the correct configuration of the Magnaflow catback?

The Magnaflow web site shows 1in & 2out the left and then one pipe curls back around to the right.

Rapid Motorsports website show the typical catback configuration with one pipe out each side.

Which is it

I'm glad I wasn't the only one confused about this when I got my Magnaflow. I'm thinking the muffler is very similar to the one for the LT-1 but upside down. I noticed that the outlet on the right is practically an immediate turn from the intlet. That's why when you stand close the right side is louder than the left. If you turned the muffler upside down and used the left outlet as the inlet. Then curled the 1 pipe around to the side it would be more even. My exhaust sounds good but I've wondered why they did this. I also feel like this is how the misconception that the Magnaflow is quiet came about. It probably was with the LT-1 configuration but not with an LS-1 with the immediate turn. It's almost like a straight pipe. lol Screams at WOT.
