I don't think so, I think the SAI is separate from this.
I have a 2000 S with stock "headers", TopSpeed test pipes, and OEM Porsche muffler, modified by FD Motorsports with their "Fister" mod. Sounds incredible. I also tried a few combinations before that, and the OEM equipment plus the test pipes does make a nice little modification in the sounds, a little "tougher" with a few more "cracks" and "burbles"

Note in that report I call the combo of stock with test pipes as "still pretty quiet", that is relative to like a loud race muffler. It is a nice little bump over pure stock.
