About 15 years ago, I read an article where something like 9 different aftermarket exhausts were tested on a 911, and although the writer wrote a few of them sounded fantastic, every one of them was inferior to the stock Porsche exhaust. In other words, in dyno testing, there were some flat-spots/loss of power etc.

Good luck!
Yes, I'm sure this was true for the NA cars, but certainly not for the 930s
