ABSOLUTE quietest muffler that flows the best
[QUOTE=Scotty-Z]Wow, you'd better listen to some other catbacks then.... 
The SLP Dual-dual muffler is by far the quietest muffler out there without compromising flow. I've heard it on a large cammed engine with LTs and an ORY and it was just barely louder than stock at idle. Even when you revved it, it still was not loud at all.

Best flow is easy to test on a bench but even still CFM @ pressure is still not exactly accurately recreating exhaust pulse or taking into effect heat. Some mufflers which out perform on the bench may not be best suited to a car just becasue of flow.
I can publish numbers of exact flow if you are curious .. i have some dynomax parts, flowmaster and MagnaFlow. If someone wants to donate shipping and some test parts i can test and send them back.

Quietest muffler= stock
If you want a quiet set up i recommend QTP electric cutout and stock catback. All else variate depending on rest of setup.
I ran Magnaflow, Borla and Hooker, Borla was the quieter with plates, then Magnaflow and Hooker just terrorised the neighbours.
