I would not discount the performance fords pipe until we see dyno plots. At least the idea is sound.
The Y-pipe does NOT need to be equal length. All it has to do is match the pulse widths.
Also bends slow the pulse down so even Perf Ford's "equal" length pipes do not have equal flow/pulses. I.E. Just added weight & heat!
I also don't see how you could say a Y-pipe "looks" raspy. (especially since all made use the same diameter (2") piping)
I tried 3 different designs and it didn't change the rasp at all (all no cat) Between them they changed the tone and drone a little, but nothing major.
