MoJo the 086 or 053 is what most of the team uses and a few use the JP2. The 2050 was the pipe most used when the Werks line first came out. It works pretty good but gives up some top end in trade for some really good fuel mileage. I haven't tried the JP3 but the JP1 was about the same as the 2050 for me. I run the JP2.
