    I have been planning on buying a muffler for my truck for about a month now since i'm tired of my loud straights. I ordered a 40 series flowmaster true duall and already have exhaust ran so should be simple. Has anyone had one of the dual in/ dual out setup and how did it sound. I'm gonna have some new 3 1/2 by 18 inch tips on the way too black gloss. If anyone has one on there truck please let me know how much you like it. Main reason for this is because my back pressure and loss of power from straights and also gas mileage. Any answers would be nice.

    I received my Flowmaster 40 series fual in/ dual out today and ordered it thursday so they sent it pretty fast with free shipping. I bought my 3 1/2 by 18 inch Black Gloss tips that are slant rolled will be here hopefully by wed. or so and then can get the exhaust and tip's put on next week. I will reply back with more info and how much i like the flow's.
