You're right. The new electric cut-outs are pretty reasonable and there's a natural place to mount them on the Z.
Actually these Valved exhaust systems work very well on NA cars. I had the "NPP" factory valved exhaust on my Vette and it was pretty awesome and made more horsepower. It actually routed the exhaust straight through the muffler when open. The one mentioned on the 3.2 Audi is not quite as refined and used primarily for meeting noise restrictions..
