All told I might still be leaning toward SW but not sure. MThis is the same "too many options" problem I've complained about before...

Again, thanks to everyone who has contributed here -- appreciate your taking the time.

 

I would love to chime in with some data on our X-Pipe system. We used to personally develop a crossover-style exhaust for many of our product lines. Through dyno testing over the many years we have been doing R&D on Porsche's, we have found the X-Pipe design to be optimal in producing the best sound and performance. We have fine tuned the "talk zone" in our X-Pipe on the various models to optimize the scavenging effect to product the most performance possible. In addition, the X design serves to smooth/even out the exhaust flow off both banks of cylinders, and provide a more refined exhaust note.

I have included one of my personal favorite videos on the basics of the X-Design for your reference. Please feel free to reach out if you have any questions I can answer for you
