Not necessarily

Ever seen a Ferrari exhaust?
It's basically one big muffler from engine to tailpipe!

There's a thought!

Chambered mufflers choke off too much performance - you'd need to build a 600hp engine to get 400hp after choking it off with all the chambered mufflers.
You want quiet?
Just don't rev over 2,000RPM.
You thinking you can rev up to redline past law enforcement?

No, but there are times I can not avoid going past 2000RPM in front of a LEO (see below)

You own a PERFORMANCE vehicle.
It's sad that you're putting noise supression a priority over performance...

It is, but I have to do what I have to do. VA is notorious when it comes to exhaust systems. I have thus far received two exhaust tickets in my lifetime in Northern Virginia. 1 was on the stock exhaust and was a "defective exhaust" never mind it was completely stock without issue, I still got a ticket. The 2 was when I was driving up hill and could not maintain 2000RPM while not impeding traffic. It most certainly is a catch 22 if you ever need an example of one.
Ted, it appears I'm getting conflicting information between you and NoDOHC. This is what he has to say in a similar thread:

The chambered muffler relies largely on acoustical wave-cancelling and is therefore very frequency specific. This is offset by selecting several or many different chamber sizes to maximize the attenuated frequencies. The wave-cancelling looks like an inductor in series and a capacitor to ground on the waveform. It resists changes in flow rate to drive a high pressure pulse which will then propagate back the pipe at a destructive phase angle. to the original sound. With several chambers, the sound can be attenuated very well. Please note that a properly-designed chambered muffler will make little to no backpressure and on a long exhaust system, they may actually decrease backpressure over a mufflerless system. Chambered mufflers rely on wave inertial energy to cancel each subsequent wave, this means that low flow rates (exhaust velocities) will hurt their attenuation performance. For this reason, it is much better to run two chambered mufflers in series than in parallel.
