I had the Nismo exhaust and Berk HFC on my 350Z, and it was one of the greatest exhaust sounds you can ever hear on a Z. Unfortunately on the 370Z you can't do that same combination and get the same results. I know because I own a 370z Nismo and tried it thinking it would sound as good as my old 350z with the same setup but it didn't. To get that sound out of the 370z you would need the HKS exhaust and Berk HFC. This is how the HKS exhaust and Berk HFC sound on the 370Z. Please watch
