In what sense? Larger stingers less torque or...?
Generally larger stingers means higher speed at the expense of low-end, but many parameters affect to this (lenght, diameter and layout of the pipe and manifold), but as a general rule:
- The longer the pipe and manifold (measured from the first chamber to the end of manifold), the better low-end.
- The larger ID of the stinger, the better high-end at expense of low-end.
Depending of the divergent and convergent cones on the pipe, this affects to the performance of the pipe. Some time ago, Motorman posted a list of pipes depending of their features. Will try to find and post them as a reference.
