Exhaust Exhaust Exhaust - Which one?

[gkmaniac]

Hi All,

I'm from Sydney, Australia and I recently purchased a 370Z Roadster and to be honest....the exhaust note is not very good. For a car of it's power and status (sports car) it definently needs to be a little louder!

I am looking for an Exhaust which delivers decent performance gains (doesn't have to be the biggest gains) but does not have an annoying drone - I basically want to give it a factory performance exhaust note under acceleration. Whilst cruising I dont want it to annoy the **** out of me however I do want it to sound a little sportier so I am open for it to be a little louder on crusing at normal speeds as well but not mind blowing as I do drive a roadster with a soft top roof.

The setups I am looking at are: (please feel free to tell me to check out other systems too!)

Stillen CBE - no HCF (I heard that with HCF it drones + way too loud)
Nismo CBE - with Berk HCF (Listening to the video clips it sounds great but not sure about droning when crusiing?)

Does the droning exist with the Nismo + Berk HCF or Stillen with no HCF setup?

Any feedback or advise would be greatly appreciated. If anyone can also provide me with a few links of where to buy these in the US or Australia that would be great as well as I want to do something in the next few days! Happy to ship from US to AU if needed.
