which one is best aftermarket exhaust?

AK370Z

How about other exhausts like Fast Intentions, ZELE, GTM Exhaust, Fujisubo, Amuse, Greddy Tic, Saclam, MCR Titnium , Surugaspeed, Invidia, Boombop, MXP etc? You need to put all those there to get a fair response.

There are two different kind of Nismo exhaust if I remember correctly. One is Nismo S-tune which bolts on to any regular 370Z. Then there's the new Nismo exhaust which is different design (hangers and piping) and DO NOT fit regular 370Zs. It's made for Nismo Z ONLY. Which Nismo are you referring to?

Also, please post threads in appropriate section. This should've been posted in "intake/Exhaust" section.
