I posted this under General Discussion, but it really belongs here. I will be getting a Magnaflow dual out installed this weekend. It will be the 5X11 2.5" dual in/dual out with 2.25" inch pipe throughout and Magnaflow 3.5" X 18" rolled edge tips angled out behind the rear wheels.
I was fooling around and found this thread on a GM Truck message board. These quicktime movie clips (click on his signature line) are the best example I have found for how the magnaflow sounds with dual out. It definitely reinforces my decision to get a Magnaflow system installed on my Titan this week. I believe the clips are from a 4.6L 2003 GMC truck. He has a 5X8 muffler 3" single in 2.5" dual out.
