looking at cat back exhaust

[millhunky]

Hey guys
A place by my work does exhaust work. They offer lifetime stainless cat back. Either flowmaster or magnaflow. Tech said would be a 44 seris on one cant remember the other. Both are 650 installed. Which one does anyone have and the sound comparison.

Thanks mark

I had 44s dumped under the cab on my z71. Im sure they would sound pretty sick on that 6.4.
