Been contemplating this since I'll be doing the second cat delete soon anyway.
Way too complicated to start hacking into a standard Boxster muffler. Won't improve the resonance (=exhaust sucking) characteristics of the exhaust either. The PSE just pipes a small fraction of direct noise to the outside world.

Yep, any information on exhaust valves would be appreciated.

Thanks for the link. You'll notice that I mentioned Pedro in the original post, so I'm well familiar with his mod and I like it. If it didn't matter for the bi-annual inspection, and if I didn't care about turning off the sound sometimes, then I would just weld up a similar mod myself. But since I can weld stainless, anything goes.

I am essentially after what you describe the PSE to be-- a little extra noise piped in. Though I'll probably go for something more aggressive, and of course with the valves to turn it on and off.

Regarding your comment about hacking into the muffler being complicated, I'm not reinventing the insides, just making a valved bypass. And I specialize in complicated.
