QUIET TURBO TYPE MUFFLERS???

You can find the optimum spot by marking the exhaust with a grease pencil or fat crayon and driving it.  Where the spot is that it isn't melted, put it there.  Of course it will be pretty far back on some, but be mindfull of crossmembers and driveshafts...

You often have to balance "optimal" with "packaging"  If you put the H or X pipe as close to the motor as you can (usually behind the transmission), you will be fine.  You likely cannot fit anything at the "optimal" location.

This is my exhaust (with the awful Walker SoundFX mufflers installed).  I cannot speak to the drone, as I never drove it before I did all the work:

I hate to hi-jack someone else's post just to ask a question.. but..

I have a set of what looks like the same mufflers.  They were about $30 each on Ebay but they weren't Walkers.. I don't think..  But the term "Sound FX" sounds familiar as to what I bought.  They are offset 2" in and out, with a marking with A <--> B on it.  I took the glasspacks off and put these Sound FX mufflers on and it sounds GREAT out the back.  The drone noise (what I consider a resonance, a hum that drowns out all other sound at a certain RPM band - mine is 1600 to 1800 RPM) it's fairly annoying at that speed.

Is the crossover pipe supposed to eliminate this resonance?  Is that the purpose?

What effect does it have out back (not that it really matters much to me..)

As far as I can tell the Sound FX mufflers sound the best on my C10 with what's basically a stock 350 without headers (stock manifold)..  The glasspacks made it sound like a bad farting boat going down the road.  Maybe that's what they were supposed to sound like.  The Sound FX made is sound like a classic street car..
