Question about crackle , pop exhaust .

[Noober]

if and when you install hfcs or cat deletes, you will hear more rasp, but will get that "pop crackle" sound you desire.
but you will also be burning more fuel and likely have a chance of turning on an engine light over time.

on my supercharged TL, i deleted all my cats and the sound was nice, no air flow restriction, but the rasp and drone almost killed it for me after awhile.
one more thing you should check is that whether or not you can still pass emissions with an aftermartket cat, or see what laws your state requires you to have to pass.

Could someone show me what test pipes or hfcs I need for Infiniti FX37S AWD

I think I need Y-pipe for AWD ? Am I right ?

HFC's and test pipes are before the Y-pipe on the exhaust so it's the same for RWD/AWD.

Do you know what test pipes he has ?

I believe they're from motordyne.
