Just exactly what happens when you switch between sport & tour on the active exhaust on the VR-4 (or stealth) ?? I've been wondering about this for ever. Can anybody shead a detailed techinical light ?? Thanks.
All it does is open a little valve to route exhaust gases to the right side tips. Nothing more nothing less. I don't remember if Dodge claims a little bit better performance with it in sport mode, but if it does I could never tell. In tour mode the exhaust tone is a little(and I mean a little) bit softer.
