Hey Dale, clarify that. My favorite muffler shop has been trying to talk me into Magnaflows for the 350 going into the '47 panel. I have a single Flowmaster (3" all the way front to back) on the 350 in the '89 Suburban and it is a sweet and mellow growl. I'm going with dual exhaust on the '47, thinking 3" pipe all the way through, and was really leaning toward the Magnaflows until you said that.
I like the construction of the Magnaflow. Fewer seams to rust out.
