The 3" exhaust wouldn't be a waste on a N/A car at all, actually. Of course, it's made for an engine with a higher exhaust output, but you will still see great high end gains with an N/A application.
If you know you're looking to stay N/A, then the 2 1/2" exhaust would be your best bet. With that, you'll consistently see great gains across the rev band as compared to the high end gains from the 3" exhaust.
As far as weight savings, we've never had the chance yet to compare the weight between the stock 370Z Exhaust to our 2 1/2" and 3" Exhaust systems. But, on average, our exhaust systems for other cars are about 10lbs lighter than the stock systems. Now, I know this isn't an exact number, but it's a ballpark figure on the weight savings.
The next opportunity we get, I'll make sure to get the weight measurements on the different exhaust systems.
