I love the DynoMax VTs. They really cut the drone down at cruise but have great sound under load. Also they are decently subdued at idle. I had flowmaster turbo 50s which were quieter in general but had a drone that really got to me after an hour or so. Now I feel I have the best of both worlds. Open it up and you get a nice loud exhaust ease off and it gets more reasonable.
I would agree you have a '69 Pump, and yes, the pressure outlet on that style is a male connection with the female connector on the hose. I have also read a '70 style uses a female fitting on the pump, but I have not seen one myself.
