My ongoing search for a deal on a 2058 pipe for my Fire 11 is not having much luck(nobody seems to run them over here..) Have found a deal on a 2013 though.. How should that match up with the F11(in general, and then in comparison to the 2058)? If anybody also happens to know how the 2013 should work on my Argus and modded Jammin JPX-21 I'd be keen to hear that too..
