Overview
The sport exhaust replaces the resonator muffler with a straight pipe and the large rear muffler with one which is freer flowing. The parts replaced by the sport exhaust system are numbers 7 and 9. The result is a very pleasant and exciting sound, it purrs at idle and rumbles during accelerations. The gain in performance is very small, most claims are between 7-10 horsepower. While this is the most expensive upgrade in the Stage 1 category, it is a necessary step in improving your Saab. The 9-3 and Viggen sport exhaust will also fit the NG900.
