The owner of a 2008 Saab 9-3 Turbo X with B284R may comment of an exhaust resonance at 2000 rpm that is more noticeable at highway cruise speeds
The 2008 9-3 Turbo X is designed with a free flow exhaust system due to the higher output of the engine. This resonance is more noticeable at highway speeds (at 2000 rpm) and can be turned on and off by manipulating the throttle. Due to the AWD, the Turbo X does not use a center muffler/silencer. This is a normal characteristic of this vehicle and no repair attempts should be made.
