Will this fit??
 

I am trying to find out if a Blitz nur spec back box will mate up to a scoobymania 3" bore centre section before I buy it any help greatly appreciated?? Or will I need the nur spec R as this is 3" bore but then just use my centre section so it is straight thru

Correct me if im wrong but I think Blitz is 2.1/2 :confused:

I got an Nur spec a while back and it reduces where it meets the centre to 2.5 inches, think you will need the Nur spec R.

So if I get a Nur spec R will it match up to a standard 3" bore scoobymania centre??? just to make it straight thru from the turbo back!!!
