Just switched out mufflers yesterday , and made sound clips of before and after. It's a BDJ's Racing 3" side exit exhaust. The first video clip is the exhaust with a 14" long 5" x 8" oval Magnaflow muffler, and the second clip is with same exhaust with a 24" long 4" round racing bullet Dynomax.

The Magnaflow was much quieter , but had a very low drone that annoyed me. They claim to sound mellow , and they do , but to me they are too mellow , taking almost all of the snaps , pops , and snarl sounds away from the car. Very smooth and non agressive sounding , and kind of a dull roar at WOT.
The Dynomax has a way more agressive sound , and will get many more cops looking your way. It is deep and menacing sounding , and lets all of the snaps and pops come through. It has no annoying buzzing like most regular resonators do , but has a nasty snarl to it. At WOT it is just really really loud , and sounds like a race car at the drag strip. The Dynomax muffler is probably the single most nasty and agressive sounding exhaust I have ever heard on a SRT-4 , and truly does give you images of a full on race car , but be warned .... the cops will know your name !
