I think F.I. did there dyno with the HFC or TP because it comes with the order when you select on there sight what it is that you want. pretty sure the CBE for our car nets around 8-10hp and the test pipes around 10-12hp correct me if im wrong. idk anything about high flow cats but im sure its in the ball park. As for performance it should be close.
good luck on the trade, hope it all works out.
