Hi all,
I'm finally pulling the plug on the exhaust upgrade for my vehicle. But now the dilemma lies in choosing between the regular ragazzon with twin pipes on one side or the group N. I found several videos, I'm amazed with the ragazzon but bear in mind that I won't be changing the centre pipe. And I couldn't find a video with the group N back box fitted with the stock centre pipe!! Is it not compatible?

Which one would you guys recommend? And If someone has fitted the group N back box without changing the centre piece please feedback me. I would be more than grateful.
