Magnaflow or Gibson? I'm not looking for loud. I want the one that provides the quietest interior sound. I see Borla also has one for the 3.7L but it's not available until mid June.

Let me rephrase my question.

For you folks with the Magnaflow and Gibson catbacks, how much did the interior noise increase after the installation as compared to stock?

Just ordered the Magnaflow -- for what it's worth with performance exhausts --- you usually can't have your cake and eat it too

Actually, I would agree. If you want the quieter one, order the Magnaflow. According to the muffler shop I bought my Flowmaster from, Magnaflow sounds almost identical to stock.

Since any cat back type system is most likely removing the resonator at the tailpipe & replacing the muffler with one of their own, I have to imagine that the Flowmaster replacement, especially the 70 series, is about the quietest of them all. I can barely hear any difference from stock at idle, it just changed the tone of it.

My Gibson from inside at idle and at cruising speeds did not change a lot. It did change, like most, when you put your foot into it.
