Not disagreeing, I am not sure, just going from experience.
Subaru typically makes really good headers though. As far as I know, there are only a couple companies that actually claim to make more power on earlier NAs and then I believe only at high RPM at the expense of the low end.
The full cat backs look to be well over $500, that is why I suggested fabbing something. I only suggested skipping the mid as they are often not a restriction or much of a baffle relative to the cat and the axle back on older turbo models was a huge restriction. Summit also has a great selection of mandrel bent pipes, flanges and mufflers for cheap. one of the few benefits of Reno.
