The 370Z is unlike the 350Z, which had a heavily restricted exhaust all the way back.

Just because its a 'true dual' when you have a Y pipe... which doesn't make sense anyways, but still... If you've seen the inside of the muffler, there are a lot of bends. Not to mention its heavy. Cat's are going to be a bottleneck on any car... I figured that was a given so it was ommitted. And have you seen the inner diameter of the Y pipe? It's TINY!!!
