If stock is in the 1-2 range, what range are the CNT and AAM exhaust in? And do these exhaust come alive at WOT?

Garageline cat back..best bang for the buck..IMOP I use my 14z as a daily and wanted good gains with minimal loudness... this was perfect for me.

I forgot to include I have 0 drone at any speed or RPM...

What kind of gains did you see from the exhaust? Do you have the graphs? How much louder than stock is it?

I don't have any dyno sheets...sorry. I inquired front the company (garageline) From what I know Garageline designed the exhaust and TurboXs built it. 2009 - 2014 TurboXS 370z Dual Catback Exhaust
This is the link... I did talk to someone from Garageline with the same numbers. I didn't realize they were talking wheel hp.....
As far as noise...slightly louder than stock...not much..just heavier...if that makes sense....no drone...and really sounds good at WOT...cruising..cant tell much different at all..
Hope this helps

Got some pictures of it on your car? Is there any rasp?

Sorry for all the questions but I am doing as much research as I can before I purchase.

On interstate, is it as quiet as stock?

no rasp at all. On interstate it is as quiet as stock until u gun it, then a little louder.. I can take some pics for u if u want. I think you should check this forum and let me know what u think.
