On our cars, since space is limited and the engine is sideways, I have been advised to just find a convinient spot that packages well and leave it at that. That comes from someone who works on prototype racing and drag vehicles. Believe it or not, your choice. 
Actually, there is a way to do it right. It won't be a good as running it on an inline engine, but you still have to match pulses or it's worse than no balance tube at all. Putting it in a place where it fits might work, might hurt. You have to check it out first with the "Crayola or Krylon" method, or know how to measure exhaust gas pulse lengths with 3 cylinders flowing in the correct firing order at the proper CFM rating and at what RPM, size of collectors, shape of collectors, length of primaries...
Go to
Burns Stainless and try to fill out a collector size report, let alone a balance tube system...
