Yes if your going to the trouble to build custom headers and have the space then equal length secondaries are an added plus. The tuned sound tells you that the pulse timing is optimized. To finish off the build I would bump the port primaries and port match the inlet flanges then also port match the T4 split plenum with that of the turbo. This match also needs to include the T4 turbo gasket. This attention to detail simply helps optimize everything. The gains are diminishing of course but using that level of detail on the entire build will make a difference.
