and I'd like to confirm that it's part number 4 in this RealOEM pic:

My system is a twin-pipe 2-piece with cat, which is why the hangar doesn't look like any of the others in RealOEM, but I know the site can be bad for mis-representing parts.
I also don't seem to have the rubber bushing for the exhaust (part 12) - the tab on the exhaust pips bolted straight to the hanger.
