Default OEM vs Borla UEL header - acoustics

I need your opinions. First, when I switched from the OEM headers to unequal length Borla knock-offs, I actually failed to hear a substantial increase in rumbleness. Granted, it was there, but rather meh - the stock catback prevented from seeing a substantial difference. On the downside, the engine bay became much more noisy, due to the headers being very thin.

Now I just got an Sti catback - and I praise it for the combination of an amazing sound, rumble and also being quiet. I dont know how much of it is due to the catback, and how much to the headers, so...

...my question: for those who , drive a model in which the headers were unequal length to start with, were smarter then me and upgraded their catback BEFORE the headers, did the Borla UELs still make a difference with respect to stock? Or can I go back to stock headers, get my engine bay silent again, yet keep the rumble?
