What exhaust sounds good for 340s?

I don't have a 340, I have a 360, I've had many moparheads locally who thought I had a 340 just because of the way she sounds.
Here's one of a while ago with a comp mutha' thumpr cam.
Straight 3 inch true duals with Summit Street & Strip mufflers.

And one from inside while my wife was driving:

It sounded good, but was a little too loud for my tastes.

So I tried for a "middle ground" approach. I put in a Lunati Voodoo cam. Dual 2.5 inch with X-pipe exhaust and Magnaflows.

A tad bit on the quiet side but it definitely roars when you punch it and rumbles nicely with moderate acceleration:

I have headers in all the videos, so those will change the sound as well vs. with OEM exhaust manifolds.
