I just purchased a Magnaflow 16929 for my ride. Took it to a few local dealers to get some estimates to bolt it up. One mechanic pointed out that I would need another hanger in the L driver side rear, as I am going from single to a new double exhaust. I attached a pic of what I need - The part looks to be rubber but I am having a hard time determining the exact part number as most of the sites have just black/white sketch drawings of the parts that aren't overly clear for smaller parts. See the pic below - thinking it might be #68105488AA ?? Any help would be great!
