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.
