I can see that the top system has an H-pipe, and seems a bit more complete. If I found a great deal on the bottom kit...would it be worth it?

 

The first link shows a Borla "True Dual" exhaust which means it has two separate pipes coming back from the cats (via an H pipe). This is the popular Borla exhaust for the 350Z which most people get if they are going with the Borla.

The second link is a single pipe exhaust just like the stock exhaust system has. Not many people get this one because if they are upgrading the exhaust, they want the benefits of a "dual exhaust". The system shown in the second link is cheaper because there are fewer pieces to it.

Unless I was going with a dual exhaust (as in the first link), I wouldn't bother changing from stock.

 

Prolly good advice, thanks!
