Very helpful! Just used this to install my new exhaust!
Agree on the WD40 or something to remove the rubber hanger pieces. I tried to remove them without and got one, but it took a lot of prying with a flat head screwdriver and a lot of elbow grease! With the WD40, it came off with just a few twists.
