In case anyone is interested...
I made a video of pics and sounds (video will make you sea-sick...sorry) of the Flowmaster Super40. It's almost 6 mins long.
VCross007 asked about part numbers for the Super40, which I don't have... so I threw this together. Hope this helps anyone interested in this exhaust setup!
