New trucks don't sound like old cars - why?

Counterpoint ><

I think the 5.2 and 5.9 Magnum exhaust manifolds sound awesome.

They flow good, too.

Just a bit of tweaking like a performance cat and cat-back duals also really adds to the sound.

My wife likes the sound too, and it's a distinctive sound, so she has learned it and usually comments when she hears one.

I just wish it was easier to adapt those to our classic SB cars with PS.

Well I cannot tell a difference in sound compared to any other modern EFI vehicle, but they certainly do flow great. IMO even the small outlet manifolds flow "as good" as the "good" 340 manifolds. The large outlet Magnum manifolds easily surpass them.
