The 2037 is a great all around pipe, great on nova based jp's and picco based engines. Twister USA has them for $70 if shipping is too expensive overseas but $60 is really hard to beat since the picture seems like it includes the pipe and manifold. Nova wants what $65 for the pipe and another $35 for the manifold or so? Picco wants even more so I won't talk about that.

I run the 2037, but it isn't as good at the Picco or IDM specific pipes on an IDM evo3 so I race with those pipes. It lacks that high end zing that you get from the more expensive pipes but they are more expensive.
