Yes, I know I'm crazy. At least my wife thinks so. If you've seen my posts the last couple months, you'll know I've been trying to figure out how to make my own PSE with valves and a switch, which I have (mostly) successfully done:
I started with a donor muffler from a 2000 S, purchased from a forum member. First it needed some polishing of course. I sourced the vacuum valves from Capristo in Germany.
The plan was to do a partial muffler bypass (think Pedro or Fister) but pipe the bypass into the outer chambers of the muffler like the PSE, and with valved control. While this ended up being very tidy, in hindsight I should have run the bypass to the tips for more sound. Version 2.0 will do this, also internally so it will retain the tidy look (and hopefully pass EU inspections.) Since I can weld, I could build it any way I wanted to, but my box lives at my second house… so I had to configure the piping without access to the car, fly down there, and hope it would fit!
The finished work:
