Dual-mode performance exhaust

The dual-mode performance exhaust with quad outlets changes its satisfying sound with the engine's rpms to give everyone fair notice that you've arrived. It utilizes a vacuum pump, along with twin valves located in the tailpipes, to provide refined tuning at low rpms, and a more aggressive exhaust sound at high engine speeds.
 
On SS models, this feature is not available with the 6-speed automatic transmission.
