Flowmaster cat back exhaust
While watching TV today, I saw a commercial about a cat back system for the Magnum that was made by FlowMaster.
Ad did show the pipe pieces and mufflers for the car, looks like another X-pipe replaces the stock suitcase muffler and the Flowmasters are mounted in the rear, near the bumper.
Upon searching their website, I saw nothing listed there for the 2005 Dodge Magnum.
I will be calling them on Monday to see what the story is.

RE: Flowmaster cat back exhaust
I forgot to mention that I already have Flowmaster series 40 mufflers on my RT, I also removed the stock resonators. Car sounds great, but I get a lot of "DRONE" in the 1700 to 2000 RPM range. I was hoping that the Flowmaster Cat Back system would elimante that drone.

RE: Flowmaster cat back exhaust
The resonator contains a specific volume of air and has a specific
length that is calculated to produce a wave that cancels out a certain
frequency of sound.
Some cars, have another component in the exhaust that looks like
a muffler, but is called a resonator. This device works just like the
resonator chamber in the muffler, the dimensions are calculated so
that the waves reflected by the resonator help cancel out certain
frequencies of sound in the exhaust.
There are other types of mufflers that can reduce backpressure. One
type, sometimes called a glass pack or a cherry bomb, uses only
absorption to reduce the sound. On a muffler like this, the exhaust
goes straight through a pipe that is perforated with holes. Surrounding
this pipe is a layer of glass insulation that absorbs some of the pressure
pulses. A steel housing surrounds the insulation. These mufflers produce
much less restriction, but don't reduce the sound level as much as
conventional mufflers.

Those design principles reminded me of how I marveled over the exhaust systems of two stroke engines on my motocross bikes of many years ago, where waves were used to retain and scavage the air / fuel mix in the cylinder.
Back to the present...with all the thought that went into the Magnum's exhaust system, it seems a shame to hack pieces off. It is a marvel of civility. However, being a romantic gear-head myself, I understand the need...
