The last one I had gave a nice little bark on startup and sounded pretty decent, except from 25 mph to 40 mph, where it reverted to noise Nazi mode. Wouldn't want to make noise in town, you know.

Porsche usually uses horsepower and consequently acceleration, to create the pecking order. They usually don't make the lesser models sound worse, or look worse, to keep us in line buying the "good Porsches."

Having had just about every variety of water-cooled Porsche aftermarket system as well as several PSE cars, I can honestly say that PSE is my least favorite "performance" exhaust system for a modern flat-six Porsche.
