Finally, I wanted to by-pass the vacuum valves entirely by using large size hose clamps to just lock the valves in the open position. After doin this and starting the car, I immediately noticed a nasty metallic rattle sound coming from the exhaust that was not there before using those clamps, so off they came.
Final question for those that have the pipes open all the time, how'd you do that?

You got it all the other way, the PSE is default on OPEN valves. As indicated in your pictures with the vaccuum line melted, the valve is on OPEN (loud) mode. To clamp the lever means to CLOSE the valve (silent mode)... Each vaccuum actuator side is independent of each other.
The plastic tubing melted due to extreme heat produced by the muffler (thus you have a heat shield)... Plastics in close proximity to heat shields IMO is just poor design... If you decide to change the melted plastic tube, i suggest that you go with silicone vaccuum lines which are more resistant to heat.
Personally, i would just leave the PSE on default/OPEN at all times by disconnecting the vaccuum lines. I dont see the need for the electric switch.
