Thanks Mitch,  that does help alot showing the change possible to the original Q..that torque increase is substantial....but according to RK's claims and what Pipe-ster has confirmed the complete new design of the 2.0 is much different yet, soooo.. we're all pretty savvy big boys here!, I think we deserve to see the hard data ....?
 
These high performance pipes are bound to start performing more like each other, for example this Q2.0 going more to the mid range like the HPR19...and now there is talk in the Hall shop of more pipe R&D as well.  It's gonna be down to splitting hairs very soon... All the more reason we need the hard data to decide which pipe best fits our style...especially when they are commanding such a big price!
