FWIW, I've heard the Patrick ones (BB) don't work so well. I'd be interested to see how the H&S ones work, but they are £1,400.00...ouch!
Talking to the guys locally, they say the B&B are better than nothing. They take the edge off, but will never toast you like the factory heat exchangers. I am running the factory heat exchangers with my 3.2 and they will roast you!!
