Just out of interest, we are selling quite a few 2072 pipes to the guys running the new orange headed Alpha motors here. It It improves the performance of the motors markedly over other pipes they have been using, and still gives great economy.
I think the Alpha 2081 is better pipe on the S852 than 2072 both in terms of power and economy. Though the 2072 might be better match on the T850 and works very well for the F850 as well. Where I see the most difference is definitely top-end. Where the 2072 starts to choke the 2081 still goes on. Anyway now that the quality issues on the pipe has been solved it's definitely something to look for in you are after a good quality overall pipe.
