I wouldn't sweat the equal pipe lengths too much. BMW even deviated from that (R1100GS/R).

And the aftermarket did it for Airheads. Luftmeister made unequal 2-into-1 systems:

Mac seems to make symmetric ones:

But if you aren't building a performance bike, why sweat it if it screws up the styling?

Here's a very elegant one that's gotten a lot of exposure:
