Sure, the chambered muffler will minimize noise - that's it's primary design criteria.
I'm arguing performance versus noise suppression.
There's two ways to suppress noise from the exhaust - choke the crap out of it or "tune" by resonance.
Resonance tuning is a lost art, and does exactly what NoDOHC mentions above.
The problem is that you cannot tune the entire RPM band out - you can only quiet RPM ranges, which can sometimes be quite narrow.
So unless you find an experienced exhaust guy that knows the car's set-up, it becomes an expensive proposition of experiementing with muffler positions to get what you want.
I always say to just stuff the biggest, honkin' muffler you can affort and fit under the car to get the best suppression.
