The NA and NB systems differ with regard to the placement of the flange which mates with the cat / midpipe. I suppose you might be able to run a complete NA-style exhaust system on an NB (everything from the turbine to the tailpipe), however bits-n-pieces of the two systems cannot be intermixed in a simple bolt-on environment.
I can assure you that a NB downpipe will not fit an NA. The Begi DP that I bought second-hand was attempted to be installed in an NA. After egg-shaping the bolt holes they finally agreed and sold it here and I bought it.
